MIC5200

100mA Low-Dropout Regulator

Features

General Description

The MIC5200 is an efﬁcient linear voltage regulator with

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

200mV at 100mA), and very low ground current (1mA at

100mA output), offering better than 1% initial accuracy with

a logic compatible ON/OFF switching input. Designed espe-

cially for hand-held battery powered devices, the MIC5200

is switched by a CMOS or TTL compatible logic signal. The

ENABLE control may be tied directly to V_INif unneeded.

When disabled, power consumption drops nearly to zero.

The ground current of the MIC5200 increases only slightly in

dropout,furtherprolongingbatterylife.KeyMIC5200features

include protection against reversed battery, current limiting,

and over-temperature shutdown.
