FEATURES

DESCRIPTION

The TPS797xx family of low-dropout (LDO) voltage

regulators offers the benefits of low-dropout voltage

and ultralow-power operation. The device is stable

with

any

capacitor

(> 0.47μF).

Therefore,

implementations of this device require very little board

space due to the miniaturized packaging and

potentially small output capacitor. In addition, the

family includes an integrated open drain active-high

power good (PG) output. Intended for use in

microcontroller-based, battery-powered applications,

the TPS797xx family low dropout and ultralow-

powered operation results in a significant increase in

system battery operating life. The small packaging

minimizes consumption of board space.

APPLICATIONS

The device is enabled when the applied voltage

exceeds the minimum input voltage. The usual PNP

pass transistor has been replaced by a PMOS pass

element. Because the PMOS pass element behaves

as a low-value resistor, the dropout voltage is very

low, typically 105mV at 10mA of load current, and is

directly proportional to the load current. The

quiescent current is ultralow (1.2μA typically) and is

stable over the entire range of output load current

(0mA to 50mA). When properly configured with a pull-

up resistor, the PG output can be used to implement

a power-on reset or low battery indicator.

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.

The OUT terminal provides the regulated output voltage of the device.

OUT

The PG terminal for the fixed voltage option devices is an open drain, active-high output that indicates

the status of V_O(output of the LDO). When V_Oexceeds approximately 90% of the regulated voltage,

PG goes to a high-impedance state. It goes to a low-impedance state when V_Ofalls below

approximately 90% (that is, overload condition) of the regulated voltage. The open drain output of the

PG terminal requires a pull-up resistor.

The IN terminal is the power supply input to the device.

SLVS332H –MARCH 2001–REVISED APRIL 2012

APPLICATION INFORMATION

The TPS797xx family of low-dropout (LDO) regulators

have been optimized for use in micropower

applications. They feature extremely low dropout

voltages and ultralow quiescent current (1.2μA

typically).

The maximum-power-dissipation limit is determined

using the following equation:

T_Jmax - T_A

P_D(max)

R_qJA

(1)

Where:

A typical application circuit is shown in Figure 14.

T_Jmax is the maximum allowable junction

temperature.

TPS797xx

R_θJAis the thermal resistance junction-to-ambient for

the package (see Package Dissipation Ratings).

100kW

T_Ais the ambient temperature.

V_OUT

OUT

The regulator dissipation is calculated using:

P_D= (V_I- V_O) x I_O

C₁

0.1mF

(2)

0.47mF

Power dissipation resulting from quiescent current is

negligible.

GND

Regulator Protection

The TPS797xx PMOS-pass transistor has a built-in

back diode that conducts reverse current when the

input voltage drops below the output voltage (for

example, during power down). Current is conducted

from the output to the input and is not internally

limited. If extended reverse voltage operation is

anticipated, external limiting might be appropriate.

Figure 14. Typical Application Circuit

External Capacitor Requirements

Although not required, a 0.1μF or larger input bypass

capacitor, connected between IN and GND and

located close to the TPS797xx, is recommended,

especially when a highly resistive power supply is

powering the LDO in addition to other devices. Like

all low-dropout regulators, the TPS797xx requires an

output capacitor connected between OUT and GND

to stabilize the internal control loop. The minimum

recommended capacitance is 0.47μF. Any 0.47μF

capacitor is suitable. Capacitor values larger than

0.47μF are acceptable.

The TPS797xx features internal current limiting.

During normal operation, the TPS797xx limits output

current to approximately 190mA. When current

limiting engages, the output voltage scales back

linearly until the overcurrent condition ends. Take

care not to exceed the power dissipation ratings of

the package.

Microcontroller Application

One application for which this device is particularly

suited is providing a regulated input voltage and

power good (PG) supervisory signal to low-power

devices such as mixed-signal microcontrollers. The

quiescent or ground current of the TPS797xx family is

typically 1.2μA even at full load; therefore, the

reduction in battery life by including the TPS797xx in

the system is negligible.

Power Dissipation and Junction Temperature

Specified regulator operation is assured to a junction

temperature of +85°C; restrict the maximum junction

temperature to +85°C under normal operating

conditions. This restriction limits the power dissipation

the regulator can handle in any given application. To

ensure the junction temperature is within acceptable

limits, calculate the maximum allowable dissipation,

P_D(MAX), and the actual dissipation, P_D, which must be

less than or equal to P_D(MAX)

IMPORTANT NOTICE

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,

and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should

obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are

sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.

TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard

warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where

mandated by government requirements, testing of all parameters of each product is not necessarily performed.

TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and

applications using TI components. To minimize the risks associated with customer products and applications, customers should provide

adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,

or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information

published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a

warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual

property of the third party, or a license from TI under the patents or other intellectual property of TI.

Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied

by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive

business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional

restrictions.

Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all

express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not

responsible or liable for any such statements.

TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably

be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing

such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and

acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products

and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be

provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in

such safety-critical applications.

TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are

specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military

specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at

the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.

TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are

designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated

products in automotive applications, TI will not be responsible for any failure to meet such requirements.
