MIC37139  
1.5A, Low-Voltage µCap LDO Regulator  
General Description  
Features  
The Micrel MIC37139 is a 1.5A low-dropout linear voltage  
regulator that provides a low-voltage, high-current output  
with a minimum of external components. It offers high preci-  
sion, ultra-low dropout (500mV overtemperature), and low  
ground current.  
1.5A minimum guaranteed output current  
500mV maximum dropout voltage overtemperature  
Ideal for 3.0V to 2.5V conversion  
Ideal for 2.5V to 1.8V, 1.65V, or 1.5V conversion  
Stable with ceramic or tantalum capacitor  
Wide input voltage range:  
The MIC37139 operates from an input of 2.25V to 6.0V. It is  
designed to drive digital circuits requiring low-voltage at high  
currents (i.e., PLDs, DSPs, microcontrollers, etc.). It is avail-  
able in fixed output voltages, including 1.5V, 1.65V, 1.8V,  
2.5V and 3.3V.  
V : 2.25V to 6.0V  
IN  
+1.0% initial output tolerance  
Fixed 1.8V output voltage  
Excellent line and load regulation specifications  
Thermal shutdown and current-limit protection  
Reverse-leakage protection  
Features of the MIC37139 LDO include thermal and current-  
limit protection, and reverse-current and reverse-battery  
protection.  
Low profile SOT-223 package  
Junction temperature range of the MIC37139 is from –40°C  
to +125°C.  
Applications  
LDO linear regulator for low-voltage digital IC  
PC add-in cards  
High-efficiency linear power supplies  
SMPS post regulator
