General Description

The MIC37501 and MIC37502 are 5A, low dropout linear voltage regulator that provide low voltage, high current outputs with a minimum of external components. They offer high precision, ultra-low dropout (500mV), and low ground current.

Features

• 5A minimum guaranteed output current

• 500mV maximum dropout voltage

– 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:

- VIN: 2.3V to 6.0V

• ±1.0% initial output tolerance

• Fixed and adjustable output voltages:

– MIC37501—7 terminal fixed voltage

– MIC37502—5 (TO-263) and 7 (SPAK) terminal adjustable voltage

• Excellent line and load regulation specifications

• Logic controlled shutdown

• Thermal shutdown and current-limit protection

• Reverse-leakage protection

• Low profile S-Pak and TO-263 packages

Applications

• LDO linear regulator for low-voltage digital IC

• PC add-in cards

• High efficiency linear power supplies

• SMPS post regulator

• Battery charger
