DESCRIPTION  
200-mA Low-Dropout (LDO) Regulator  
With Enable (EN)  
The TPS799xx family of low-dropout (LDO)  
low-power linear regulators offers excellent ac  
performance with very low ground current. High  
power-supply rejection ratio (PSRR), low noise, fast  
start-up, and excellent line and load transient  
response are provided while consuming a very low  
40-μA (typical) ground current. The TPS799xx is  
stable with ceramic capacitors and uses an advanced  
BiCMOS fabrication process to yield a dropout  
voltage of 100 mV (typ) at 200-mA output. The  
TPS799xx uses a precision voltage reference and  
feedback loop to achieve overall accuracy of 2% over  
all load, line, process, and temperature variations. It  
is fully specified from TJ = 40°C to 125°C and is  
offered in low profile ThinSOT-23 and 2-mm × 2-mm  
SON packages, ideal for wireless handsets and  
WLAN cards.  
Low IQ: 40 μA  
Multiple Output Voltage Versions Available:  
Fixed Outputs of 1.2 V to 4.5 V Using  
Innovative Factory EEPROM Programming  
Adjustable Outputs from 1.2 V to 6.5 V  
High PSRR: 66 dB at 1 kHz  
Ultralow Noise: 29.5 μVRMS  
Fast Start-Up Time: 45 μs  
Stable With a Low ESR, 2-μF (Typ) Output  
Capacitance  
Excellent Load/Line Transient Response

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with  
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.  
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more  
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

SBVS097E MARCH 2008REVISED JANUARY 2012  
APPLICATION INFORMATION  
The TPS799xx family of LDO regulators combines the high performance required of many RF and precision  
analog applications with ultra-low current consumption. High PSRR is provided by a high gain, high bandwidth  
error loop with good supply rejection at very low headroom (VIN VOUT). Fixed voltage versions provide a noise  
reduction pin to bypass noise generated by the bandgap reference and to improve PSRR while a quick-start  
circuit fast-charges this capacitor at startup. The combination of high performance and low ground current also  
make the TPS799xx an excellent choice for portable applications. All versions have thermal and over-current  
protection and are fully specified from 40°C to 125°C.  
Figure 12 shows the basic circuit connections for fixed-voltage model. Figure 13 gives the connections for the  
adjustable output version (TPS79901). R1 and R2 can be calculated for any output voltage using the formula in  
Figure 13. Sample resistor values for common output voltages are shown in Figure 13.  
Input and Output Capacitor Requirements  
Although an input capacitor is not required for stability, it is good analog design practice to connect a 0.1-μF to  
1-μF low ESR capacitor across the input supply near the regulator. This counteracts reactive input sources and  
improve transient response, noise rejection, and ripple rejection. A higher-value capacitor may be necessary if  
large, fast rise-time load transients are anticipated or the device is located several inches from the power source.  
If source impedance is not sufficiently low, a 0.1-μF input capacitor may be necessary to ensure stability.  
The TPS799xx is designed to be stable with standard ceramic capacitors of values 2.2 μF or larger. X5R and  
X7R type capacitors are best as they have minimal variation in value and ESR over temperature. Maximum ESR  
should be <1.0 .  
Feedback Capacitor Requirements (TPS79901 only)  
The feedback capacitor, CFB, shown in Figure 13 is required for stability. For a parallel combination of R1 and R2  
equal to 250 k, any value from 3 pF to 1 nF can be used. Fixed voltage versions have an internal 30-pF  
feedback capacitor which is quick-charged at start-up. The adjustable version does not have this quick-charge  
circuit, so values below 5 pF should be used to ensure fast startup; values above 47 pF can be used to  
implement an output voltage soft-start. Larger value capacitors also improve noise slightly. The TPS79901 is  
stable in unity-gain configuration (OUT tied to FB) without CFB  
.
Output Noise  
In most LDOs, the bandgap is the dominant noise source. If a noise reduction capacitor (CNR) is used with the  
TPS799xx, the bandgap does not contribute significantly to noise. Instead, noise is dominated by the output  
resistor divider and the error amplifier input. To minimize noise in a given application, use a 0.01-μF noise  
reduction capacitor; for the adjustable version, smaller value resistors in the output resistor divider reduce noise.  
A parallel combination that gives 2 μA of divider current has the same noise performance as a fixed-voltage  
version. To further optimize noise, equivalent series resistance of the output capacitor can be set to  
approximately 0.2 . This configuration maximizes phase margin in the control loop, reducing total output noise  
by up to 10%.

The TPS79901 adjustable version does not have the noise-reduction pin available, so ultra-low noise operation is  
not possible. Noise can be minimized according to the previous recommendations.  
Board Layout Recommendations to Improve PSRR and Noise Performance  
To improve ac performance such as PSRR, output noise, and transient response, it is recommended that the  
board be designed with separate ground planes for VIN and VOUT, with each ground plane connected only at the  
GND pin of the device. In addition, the ground connection for the bypass capacitor should connect directly to the  
GND pin of the device.  
Internal Current Limit  
The TPS799xx internal current limit helps protect the regulator during fault conditions. During current limit, the  
output sources a fixed amount of current that is largely independent of output voltage. For reliable operation, the  
device should not be operated in current limit for extended periods of time.  
The PMOS pass element in the TPS799xx has a built-in body diode that conducts current when the voltage at  
OUT exceeds the voltage at IN. This current is not limited, so if extended reverse voltage operation is  
anticipated, external limiting may be appropriate.  
Shutdown  
The enable pin (EN) is active high and is compatible with standard and low voltage TTL-CMOS levels. When  
shutdown capability is not required, EN can be connected to IN.  
Dropout Voltage  
The TPS799xx uses a PMOS pass transistor to achieve low dropout. When (VIN VOUT) is less than the dropout  
voltage (VDO), the PMOS pass device is in its linear region of operation and the input-to-output resistance is the  
RDS, ON of the PMOS pass element. Because the PMOS device behaves like a resistor in dropout, VDO scales  
approximately with output current.  
As with any linear regulator, PSRR and transient response are degraded as (VIN VOUT) approaches dropout.  
This effect is shown in Figure 9 through Figure 11 in the Typical Characteristics section.  
Startup  
Fixed voltage versions of the TPS799xx use a quick-start circuit to fast-charge the noise reduction capacitor,  
CNR, if present (see Functional Block Diagrams, Figure 1). This allows the combination of very low output noise  
and fast start-up times. The NR pin is high impedance so a low leakage CNR capacitor must be used; most  
ceramic capacitors are appropriate in this configuration.  
Note that for fastest startup, VIN should be applied first, then the enable pin (EN) driven high. If EN is tied to IN,  
startup is somewhat slower. The quick-start switch is closed for approximately 135 μs. To ensure that CNR is fully  
charged during the quick-start time, a 0.01 μF or smaller capacitor should be used.  
Transient Response  
As with any regulator, increasing the size of the output capacitor reduces over/undershoot magnitude but  
increase duration of the transient response. In the adjustable version, adding CFB between OUT and FB  
improves stability and transient response. The transient response of the TPS799xx is enhanced by an active  
pulldown that engages when the output overshoots by approximately 5% or more when the device is enabled.  
When enabled, the pulldown device behaves like a 350-resistor to ground.  
Undervoltage Lockout (UVLO)  
The TPS799xx utilizes a UVLO circuit to keep the output shut off until internal circuitry is operating properly. The  
UVLO circuit has a deglitch feature so that it typically ignores undershoot transients on the input if they are less  
than 50-μs duration.

SBVS097E MARCH 2008REVISED JANUARY 2012  
Minimum Load  
The TPS799xx is stable and well behaved with no output load. To meet the specified accuracy, a minimum load  
of 500 μA is required. Below 500 μA at junction temperatures near 125°C, the output can drift up enough to  
cause the output pulldown to turn on. The output pulldown limits voltage drift to 5% typically, but ground current  
could increase by approximately 50 μA. In typical applications, the junction cannot reach high temperatures at  
light loads since there is no appreciable dissipated power. The specified ground current would then be valid at no  
load in most applications.  
THERMAL INFORMATION  
Thermal Protection  
Thermal protection disables the output when the junction temperature rises to approximately 165°C, allowing the  
device to cool. When the junction temperature cools to approximately 145°C, the output circuitry is again  
enabled. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection  
circuit may cycle on and off. This cycling limits the dissipation of the regulator, protecting it from damage due to  
overheating.  
Any tendency to activate the thermal protection circuit indicates excessive power dissipation or an inadequate  
heatsink. For reliable operation, junction temperature should be limited to 125°C maximum. To estimate the  
margin of safety in a complete design (including heatsink), increase the ambient temperature until the thermal  
protection is triggered; use worst-case loads and signal conditions. For good reliability, thermal protection should  
trigger at least 35°C above the maximum expected ambient condition of your particular application. This  
configuration produces a worst-case junction temperature of 125°C at the highest expected ambient temperature  
and worst-case load.  
The internal protection circuitry of the TPS799xx has been designed to protect against overload conditions. It  
was not intended to replace proper heatsinking. Continuously running the TPS799xx into thermal shutdown  
degrades device reliability.  
Power Dissipation  
The ability to remove heat from the die is different for each package type, presenting different considerations in  
the PCB layout. The PCB area around the device that is free of other components moves the head from the  
device to the ambient air. Performance data for JEDEC low- and high-K boards are given in the Thermal  
Information table. Using heavier copper increases the effectiveness in removing heat from the device. The  
addition of plated through holes to heat-dissipating layers also improves the heatsink effectiveness.  
Power dissipation depends on input voltage and load conditions. Power dissipation is equal to the product of the  
output current times the voltage drop across the output pass element, as shown in Equation 2:
