MIC5235

Ultra-Low Quiescent Current, 150mA

µCap LDO Regulator

General Description

Features

The MIC5235 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 MIC5235 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: 310mV at 150mA

• High output accuracy: ±2.0% over temperature

• µCap: stable with ceramic or tantalum capacitors

• Excellent line and load regulation specifications

• Zero shutdown current

• Reverse battery protection

• Reverse leakage protection

• Thermal shutdown and current limit protection

• IttyBitty^®SOT-23-5 package

• Adjustable output from 1.24V-20V

A µCap LDO design, the MIC5235 is stable with either

ceramic or tantalum output capacitor. It only requires a

2.2µF capacitor for stability.

Features of the MIC5235 includes enable input, thermal

shutdown, current limit, reverse battery protection, and

reverse leakage protection.

Available in fixed and adjustable output voltage versions,

the MIC5235 is offered in the IttyBitty^®SOT-23-5 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
