MIC5225

Ultra-Low Quiescent Current

150mA µCap Low Dropout Regulator

General Description

Features

The MIC5225 is a 150mA highly accurate, low dropout

regulator with high input voltage and ultra-low ground

current. This combination of high voltage and low ground

current makes the MIC5225 ideal for a wide variety of

applications including USB and portable electronics

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

inputs.

• Wide input voltage range: 2.3V to 16V

• High output accuracy of ±2.0% over temperature

• Guaranteed 150mA output

• Very low ground current: 29µA

• Low dropout voltage of 310mV at 150mA

• µCap: Stable with ceramic or tantalum capacitors

• Excellent line and load regulation specifications

• Reverse battery protection

• Reverse leakage protection

• Zero shutdown current

A µCap LDO design, the MIC5225 is stable with either a

ceramic or tantalum output capacitor. It only requires a

2.2µF capacitor for stability.

Features of the MIC5225 includes enable input, thermal

shutdown, current limit, reverse battery protection, and

reverse leakage protection.

• Thermal shutdown and current limit protection

• IttyBitty^®SOT23-5 Package

Available in fixed and adjustable output voltage versions,

the MIC5225 is offered in the IttyBitty^®SOT23-5 package

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

Applications
