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  
precision, ultra-low dropout (500mV overtemperature), and  
low ground current.  
1.5A minimum guaranteed output current  
500mV maximum dropout voltage over temperature  
Stable with ceramic or tantalum capacitor  
Wide input voltage range: VIN:2.25V to 6.0V  
+1.0% initial output tolerance  
The MIC37139 operates from an input of 2.25V to 6.0V. It  
is designed for a wide variety of applications including  
digital circuits requiring low-voltage at high currents (i.e.,  
PLDs, DSPs, microcontrollers, etc.). It is available in a  
fixed output voltage of 1.8V, and as low as 1.5V.  
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. It’s junction temperature range of the is  
from –40°C to +125°C.  
Low profile SOT-223 package
