MIC5202

Dual 100mA Low-Dropout Voltage Regulator

Preliminary Information

General Description

Features

The MIC5202 is a family of dual linear voltage regulators with

very low dropout voltage (typically 17mV at light loads and

210mV at 100mA), and very low ground current (1mA at

100mA output–each section), offering better than 1% initial

accuracy with a logic compatible ON/OFF switching input.

Designed especially for hand-held battery powered devices,

the MIC5202 is switched by a CMOS or TTL compatible logic

signal. This ENABLE control my be tied directly to V if

unneeded. When disabled, power consumption drops nearly

to zero. The ground current of the MIC5202 increases only

slightlyindropout,furtherprolongingbatterylife. KeyMIC5202

features include protection against reversed battery, current

limiting, and over-temperature shutdown.

Logic-controlled electronic shutdown

Available in SO-8 package

Applications

The MIC5202 is available in several fixed voltages. Other

options are available; contact Micrel for details.
