MIC2920A/29201/29202/29204 Micrel, Inc. MIC2920A/29201/29202/29204
400mA Low-Dropout Voltage Regulator General Description Features The MIC2920A family are “bulletproof,” efficient voltage regulators with very low dropout voltage (typically 40mV at light
loads and 370mV at 250mA), and very low quiescent current
(140ВµA typical). The quiescent current of the MIC2920A increases only slightly in dropout, prolonging battery life. Key
MIC2920A features include protection against reversed battery, fold-back current limiting, and automotive “load dump”
protection (60V positive transient). The MIC2920 is available in several configurations. The
MIC2920A-x.x devices are three pin п¬Ѓxed voltage regulators
available in 3.3V, 4.85V, 5V, and 12V outputs. The MIC29201
is a fixed regulator offering a logic compatible ON/OFF (shutdown) input and an error flag output. This flag may also be
used as a power-on reset signal. A logic-compatible shutdown
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
flag pins and may be pin-strapped for 5V output or programmed
from 1.24V to 26V using two external resistors. High output voltage accuracy
