MIC5202

General Description

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

needed. When disabled, power consumption drops nearly

to zero. The ground current of the MIC5202 increases only

slightly in dropout, further prolonging battery life. Key MIC5202

features include protection against reversed battery, current

limiting, and over-temperature shutdown.

The MIC5202 is available in several ﬁ xed voltages. Other

options are available; contact Micrel for details.
