MIC37300/01/02/03  
3.0A, Low-Voltage µCap LDO Regulator  
General Description  
Features  
The Micrel MIC37300/01/02/03 is a 3.0A low-dropout  
linear voltage regulator that provides a low-voltage,  
high-current output with a minimum number of external  
components. It offers high precision, ultra-low-dropout  
(500mV overtemperature), and low-ground current.  
3.0A 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 MIC37300/01/02/03 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, DSP,  
microcontroller, etc.). It is available in xed and  
adjustable output voltages. Fixed voltages include 1.5V,  
1.8V, 2.5V and 3.3V. The adjustable version is capable  
of 1.24V to 5.5V.  
VIN: 2.25V to 6.0V  
+1.0% initial output tolerance  
Fixed and adjustable output voltages:  
MIC37300—3-pin xed voltages  
MIC37301—5-pin S-Pak or 8-pin e-Pad SOIC  
xed voltages with ag  
Features of the MIC37300/01/02/03 LDO include  
thermal and current-limit protection, and reverse-current  
protection. Logic enable and error ag pins are available  
on the 5-pin version.  
MIC37302—5-pin adjustable voltage  
MIC37303—8-pin e-Pad SOIC adjustable  
voltage with flag  
Excellent line and load regulation specications  
Thermal shutdown and current-limit protection  
Reverse-leakage protection  
Junction temperature range of the MIC37300/01/02/03  
is from–40°C to +125°C.  
For applications requiring input voltage greater than  
6.0V, see the MIC3910x, MIC3915x, MIC3930x, and  
MIC3950x LDOs.  
Low prole S-Pak package
