MIC37501/37502

5A, Low Voltage μCap LDO Regulator

General Description

Features

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.

• 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

The MIC37501and MIC37502 operate from an input of

2.3V to 6.0V. They are designed to drive digital circuits

requiring low voltage at high currents (i.e., PLDs, DSPs,

microcontrollers, etc.). They are available in fixed and

adjustable output voltages. Fixed voltages include 1.5V,

1.65V, 1.8V, 2.5V, and 3.3V. The adjustable version is

capable of 1.24V to 5.5V.

• Stable with ceramic or tantalum capacitor

• Wide input voltage range:

- V_IN: 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

MIC37501 and MIC37502 LDOs feature thermal and

currentlimit protection and reverse current protection.

Logic enable and error flag pins are available.

Junction temperature range of the MIC37501/02 is from

–40°C to 125°C.

For applications requiring input voltage greater than

6.0V, see MIC3910x, MIC3915x, MIC3930x, and

MIC3950x LDOs.
