MIC5295

Low Quiescent Current, 150mA LDO

Regulator

General Description

Features

The MIC5295 is a 150mA highly accurate, low dropout

regulator with high input voltage and low ground current.

This combination of high voltage and low ground current

makes the MIC5295 ideal for USB and portable electronics

applications, using 1-cell, 2-cell or 3-cell Li-Ion battery

inputs.

• Wide input voltage range: 2.3V to 24V

• Ultra low ground current: 18µA

• Low dropout voltage: 300mV at 150mA

• High initial output accuracy: ±1.0%

• Stable with ceramic or tantalum capacitors

• Excellent line and load regulation specifications

• Reverse battery protection

A µCap LDO design, the MIC5295 is stable with either a

ceramic or tantalum output capacitor. It only requires a

2.2µF capacitor for stability.

• Reverse leakage protection

Features of the MIC5295 includes enable input, thermal

shutdown, current limit, reverse battery protection, and

reverse leakage protection.

• Thermal shutdown and current limit protection

• PowerTO-252-5 (D-Pak)package

• Adjustable output from 1.24V-20V

Available in fixed and adjustable output voltage versions,

the MIC5295 is offered in the TO-252-5 (D-Pak) package

with a junction temperature range of –40°C to +125°C.

Applications

• USB power supply

• Cellular phones

• Keep-alive supply in notebook and portable computers

• Logic supply for high-voltage batteries

• Automotive electronics

• Battery powered systems
