MIC37252  
2.5A, Low Voltage µCap LDO Regulator  
Final  
General Description  
Features  
The Micrel MIC37252 is a 2.5A low-dropout linear voltage  
regulator that provides a low voltage, high current output with  
a minimum of external components. It offers high precision,  
low dropout and low ground current.  
• 2.5A minimum guaranteed output current  
Ideal for 3.3V to 1.8V conversion  
• Stable with ceramic or tantalum capacitor  
• +2.0% initial output tolerance  
• Dropout voltage = 550mV @ 2.5A  
• Excellent line and load regulation specifications  
• Logic controlled shutdown  
• Thermal shutdown and current limit protection  
• Reverse-leakage protection  
The MIC37252 operates from an input voltage of 3.0V 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 an adjustable output voltage capable of  
1.24V to 5.5V.  
• S-Pak and TO-263 packages  
Features of the MIC37252 LDO include thermal and current  
limit protection, and reverse current and reverse battery  
protection.  
Applications  
• LDO linear regulator for low-voltage digital IC  
• PC add-in cards  
• High efficiency linear power supplies  
• SMPS post regulator  
• Battery charger  
Junction temperature range of the MIC37252 is from –40°C  
to 125°C.  
For higher currents see the MIC3730x family of LDOs.
