Micrel, Inc.

MIC2920A/29201/29202/29204

400mA Low-Dropout Voltage Regulator

General Description

Features

•

High output voltage accuracy

The MIC2920Afamily are “bulletproof,” efﬁcient voltage regu-

lators with very low dropout voltage (typically 40mV at light

loads and 370mV at 250mA), and very low quiescent current

(140µA typical). The quiescent current of the MIC2920A in-

creases only slightly in dropout, prolonging battery life. Key

MIC2920A features include protection against reversed bat-

tery, fold-back current limiting, and automotive “load dump”

protection (60V positive transient).

Guaranteed 400mA output

Low quiescent current

Low dropout voltage

Extremely tight load and line regulation

Very low temperature coefﬁcient

Current and thermal limiting

Input withstands –20V reverse battery and

60V positive transients

The MIC2920 is available in several conﬁgurations. The

MIC2920A-x.x devices are three pin ﬁxed voltage regulators

available in 3.3V, 4.85V, 5V, and 12V outputs. The MIC29201

is a ﬁxed regulator offering a logic compatible ON/OFF (shut-

down) input and an error ﬂag output. This ﬂag may also be

usedasapower-onresetsignal.Alogic-compatibleshutdown

input is provided on the adjustable MIC29202 which allows

the regulator to be switched on and off. The MIC29204 8-pin

SOIC adjustable regulator includes both shutdown and error

ﬂagpinsandmaybepin-strappedfor5Voutputorprogrammed

from 1.24V to 26V using two external resistors.

Error ﬂag warns of output dropout

Logic-controlled electronic shutdown

Output programmable from 1.24V to 26V

(MIC29202/MIC29204)

Available in TO-220-3, TO-220-5, and surface-mount

TO-263-5, SOT-223, and SO-8 packages.
