MIC2915X/30X/50X/75X  
High-Current Low Dropout Regulators  
Features  
General Description  
• High Current Capability:  
The MIC2915x/2930x/2950x/2975x are high current,  
high accuracy, low dropout voltage regulators. Using  
Microchip’s proprietary Super βeta PNP process with a  
PNP pass element, these regulators feature 350 mV to  
425 mV (full load) typical dropout voltages and very low  
ground current. Designed for high current loads, these  
devices also find applications in lower current,  
extremely low dropout-critical systems, where their tiny  
dropout voltage and ground current values are  
important attributes.  
- MIC29150/29151/29152/29153: 1.5A  
- MIC29300/29301/29302/29303: 3A  
- MIC29500/29501/29502/29503: 5A  
- MIC29751/29752: 7.5A  
• Low Dropout Voltage  
• Low Ground Current  
• Accurate 1% Guaranteed Tolerance  
• Extremely Fast Transient Response  
• Reverse-Battery and “Load Dump” Protection  
• Zero-Current Shutdown Mode (5-Pin Versions)  
The MIC2915x/2930x/2950x/2975x are fully protected  
against overcurrent faults, reversed input polarity,  
reversed lead insertion, overtemperature operation,  
and positive and negative transient voltage spikes. Five  
pin fixed-voltage versions feature logic level ON/OFF  
control and an error flag that signals whenever the  
output falls out of regulation. Flagged states include  
low input voltage (dropout), output current limit,  
overtemperature shutdown, and extremely high voltage  
spikes on the input.

• High-Efficiency Green Computer Systems  
• Automotive Electronics  
On the MIC29xx1 and MIC29xx2, the ENABLE pin may  
be tied to VIN if it is not required for ON/OFF control.  
The MIC2915x/2930x/2950x are available in 3-pin and  
5-pin TO-220 and surface mount TO-263 (D2Pak)  
packages. The MIC2975x 7.5A regulators are available  
in a 5-pin TO-247 package. The 1.5A, adjustable output  
MIC29152 is available in a 5-pin power D-Pak

Note 1: Specification for packaged product only.  
2: When used in dual supply systems where the regulator load is returned to a negative supply, the output  
voltage must be diode clamped to ground.  
3: Full load current (IFL) is defined as 1.5A for the MIC2915x, 3A for the MIC2930x, 5A for the MIC2950x,  
and 7.5A for the MIC2975x families.  
4: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total  
temperature range.  
5: Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its  
normal value with VOUT + 1V applied to VIN.  
6: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum  
of the load current plus the ground pin current.  
7: VIN = VOUT (nominal) + 1V. For example, use VIN = 4.3V for a 3.3V regulator or use 6V for a 5V regulator.  
Employ pulse-testing procedures to pin current.  
8: VREF VOUT (VIN – 1V), 2.3V VIN 26V, 10 mA < IL IFL, TJ TJMAX  
.
9: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipa-  
tion is applied, excluding load or line regulation effects. Specifications are for a 200 mA load pulse at VIN  
20V (a 4W pulse) for T = 10 ms.  
=
10: Comparator thresholds are expressed in terms of a voltage differential at the adjust terminal below the  
nominal reference voltage measured at 6V input. To express these thresholds in terms of output voltage  
change, multiply by the error amplifier gain = VOUT/VREF = (R1 + R2)/R2. For example, at a programmed  
output voltage of 5V, the error output is guaranteed to go low when the output drops by 95 mV x  
5V/1.240V = 384 mV. Thresholds remain constant as a percent of VOUT as VOUT is varied, with the drop-  
out warning occurring at typically 5% below nominal, 7.7% guaranteed.

Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable  
junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the  
maximum allowable power dissipation will cause the device operating junction temperature to exceed the  
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.

Thermal Design  
4.0  
APPLICATION INFORMATION  
Linear regulators are simple to use. The most  
complicated design parameters to consider are thermal  
characteristics. Thermal design requires the following  
application-specific parameters:  
The MIC2915x, MIC2930x, MIC2950x, and MIC2975x  
are high-performance low-dropout voltage regulators  
suitable for all moderate to high-current voltage  
regulator applications. Their 350 mV to 425 mV typical  
dropout voltage at full load make them especially  
valuable in battery powered systems and as high  
efficiency noise filters in post-regulator applications.  
Unlike older NPN-pass transistor designs, where the  
minimum dropout voltage is limited by the base-emitter  
voltage drop and collector-emitter saturation voltage,  
dropout performance of the PNP output of these  
devices is limited merely by the low VCE saturation  
voltage.  
• Maximum Ambient Temperature, TA  
• Output Current, IOUT  
• Output Voltage, VOUT  
• Input Voltage, VIN  
First, calculate the power dissipation of the regulator  
from these numbers and the device parameters from  
this data sheet.  
EQUATION 4-1:  
A trade-off for the low-dropout voltage is a varying base  
driver requirement. But Microchip’s Super ßeta PNP  
process reduces this drive requirement to merely 1% of  
the load current.  
PD = IOUT1.01VIN VOUT  
The MIC2915x/2930x/2950x/2975x family of regulators  
are fully protected from damage due to fault conditions.  
Current limiting is provided. This limiting is linear;  
output current under overload conditions is constant.  
Thermal shutdown disables the device when the die  
temperature exceeds the +125°C maximum safe  
operating temperature. Line transient protection allows  
device and load survival even when the input voltage  
spikes between –20V and +60V. When the input  
voltage exceeds approximately 32V, the overvoltage  
sensor disables the regulator. The output structure of  
these regulators allows voltages in excess of the  
desired output voltage to be applied without reverse  
current flow. MIC29xx1 and MIC29xx2 versions offer a  
logic-level ON/OFF control. When disabled, the  
devices draw nearly zero current.  
The ground current is approximated by 1% of IOUT  
Then the heat sink thermal resistance is determined  
with Equation 4-2.  
.
EQUATION 4-2:  
TJMAX TA  
SA = ---------------------------- JC + CS  
PD  
Where:  
TJMAX 125°C  
An additional feature of this regulator family is a  
common pinout. A design’s current requirement may  
change up or down, but use the same board layout  
because all of these regulators have identical pinouts.  
θCS Between 0°C/W and 2°C/W  
The heat sink may be significantly reduced in  
applications where the minimum input voltage is known  
and is large compared with the dropout voltage. Use a  
series input resistor to drop excessive voltage and  
distribute the heat between this resistor and the  
regulator. The low-dropout properties of Super ßeta  
PNP regulators allow very significant reductions in  
regulator power dissipation and the associated heat  
sink without compromising performance. When this  
technique is employed, a capacitor of at least 0.1 µF is  
needed directly between the input and regulator  
ground.

With no heat sink in the application, calculate the  
junction temperature to determine the maximum power  
dissipation that will be allowed before exceeding the  
maximum junction temperature of the MIC29152. The  
maximum power allowed can be calculated using the

thermal resistance (θJA) of the D-Pak adhering to the  
following criteria for the PCB design: 2 oz. copper and  
100 mm2 copper area for the MIC29152.  
This capacitor need not be an expensive low ESR type:  
aluminum electrolytics are adequate. In fact, extremely  
low ESR capacitors may contribute to instability.  
Tantalum capacitors are recommended for systems  
where fast load transient response is important.  
For example, given an expected maximum ambient  
temperature (TA) of +75°C with VIN = 3.3V, VOUT  
=
2.5V, and IOUT = 1.5A, first calculate the expected PD  
using Equation 4-3:  
Where the regulator is powered from a source with high  
AC impedance, a 0.1 µF capacitor connected between  
Input and GND is recommended. This capacitor should  
have good characteristics to above 250 kHz.

Minimum Load Current  
PD = 3.3V – 2.5V  1.5A 3.3V 0.016A= 1.1472W  
The MIC2915x–2975x regulators are specified  
between finite loads. If the output current is too small,  
leakage currents dominate and the output voltage  
rises. The following minimum load current swamps any  
expected leakage current across the operating  
temperature range, as shown in Table 4-2.  
Next, calculate the junction temperature for the  
expected power dissipation.

Now determine the maximum power dissipation  
allowed that would not exceed the IC’s maximum  
junction temperature (+125°C) without the use of a  
heat sink.

Adjustable Regulator Design  
The adjustable regulator versions, MIC29xx2 and  
MIC29xx3, allow programming the output voltage  
anywhere between 1.25V and the 25V. Two resistors  
are used. The resistor values are calculated by  
Equation 4-6.

Capacitor Requirements

For stability and minimum output noise, a capacitor on  
the regulator output is necessary. The value of this  
capacitor is dependent upon the output current; lower  
currents  
allow  
smaller  
capacitors.  
The  
In the equation above, VOUT is the desired output  
voltage. Figure 4-2 shows component definition.  
Applications with widely varying load currents may  
scale the resistors to draw the minimum load current  
required for proper operation (see the Minimum Load  
Current sub-section).  
MIC2915x/2930x/2950x/2975x regulators are stable  
with the following minimum capacitor values at full load,

Error Flag  
MIC29xx1 and MIC29xx3 versions feature an Error  
Flag, which looks at the output voltage and signals an  
error condition when this voltage drops 5% below its  
expected value. The error flag is an open-collector  
output that pulls low under fault conditions. It may sink  
10 mA. Low output voltage signifies a number of  
possible problems, including an overcurrent fault (the  
device is in current-limit) and low input voltage. The flag  
output is inoperative during overtemperature shutdown  
conditions.  
4.6  
Enable Input  
MIC29xx1 and MIC29xx2 versions feature an enable  
(EN) input that allows ON/OFF control of the device.  
Special design allows “zero” current drain when the  
device is disabled; only microamperes of leakage  
current flows. The EN input has TTL/CMOS compatible  
thresholds for simple interfacing with logic, or may be  
directly tied to 30V. Enabling the regulator requires  
approximately 20 µA of current.
