MIC37100/37101/37102  
1A Low-Voltage µCap LDO  
General Description  
Features  
The MIC37100, MIC37101, and MIC37102 are 1A low-  
dropout, linear voltage regulators that provide low-voltage,  
high-current output from an extremely small package.  
Utilizing Micrel’s proprietary Super βeta PNP® pass  
element, the MIC37100/01/02 offers extremely low dropout  
(typically 280mV at 1A) and low ground current (typically  
11mA at 1A).  
Fixed and adjustable output voltages to 1.24V  
µCap Regulator, 10µF ceramic output capacitor stable  
280mV typical dropout at 1A  
Ideal for 3.0V to 2.5V conversion  
Ideal for 2.5V to 1.8V, 1.65V or 1.5V conversion  
1A minimum guaranteed output current  
1% initial accuracy  
Low ground current  
Current limiting and thermal shutdown  
Reversed-leakage protection  
Fast transient response  
Low-prole SOT-223 package  
Power SO-8 package  
The MIC37100 is a xed output regulator offered in the  
SOT-223 package. The MIC37101 and MIC37102 are  
xed and adjustable regulators, respectively, in a thermally  
enhanced power 8-pin SOIC (small outline package) and  
the SOT-223 package. The MIC37102 is also available in  
the S-PAK power package, for applications that require  
higher power dissipation or higher operating ambient  
temperatures.  
S-PAK package (MIC37102 only)  
The MIC37100/01/02 is ideal for PC add-in cards that  
need to convert from standard 5V to 3.3V, 3.3V to 2.5V or  
2.5V to 1.8V or lower. A guaranteed maximum dropout  
voltage of 500mV over all operating conditions allows the  
MIC37100/01/02 to provide 2.5V from a supply as low as  
3V and 1.8V from a supply as low as 2.3V.  
Applications  
LDO linear regulator for PC add-in cards  
PowerPC® power supplies  
The MIC37100/01/02 is fully protected with overcurrent  
limiting and thermal shutdown. Fixed output voltages of  
1.5V, 1.65V, 1.8V, 2.5V and 3.3V are available on  
MIC37100/01 with adjustable output voltages to 1.24V on  
MIC37102.  
High-efciency linear power supplies  
SMPS post regulator  
Multimedia and PC processor supplies  
Battery chargers  
Low-voltage microcontrollers and digital logic
