¡El MIC2920A family are "bulletproof" efficient voltageregulators with very low drop out voltage (typically 40mV atlight loads and 370mV at 250mA), and very low quiescentcurrent ( 140uA typical). ¡El quiescentcurrentof theMIC2920Aincreases only slightly in dropout, thus proionging battery life.Key MIC2920A features include protection against reversedbattery, fold-back current limiting,and automotive "load dump"protection (6ov positive transient). ¡El MIC2920 is available in several configurations. TheMIC2920A-xx devices are three pin fixed voltage regulatorsavailable in 3.3V,4.85V, 5V, and 12V outputs.¡El MIC29201is a fixed regulator offering logiccompatible ON/OFFswitchinginput and an error flag output.This flag may also be used asa power-on reset signal. A logic-compatible shutdown input isprovided on the adjustable MIC29202,which enables theregulator to be switched on and off.¡El MIC29203 is a five pinadjustable version that includes anerror flag output that warnsof a low output voltage, which is often due to failing batterieson the input.¡El eight pin DIP and sOIC adjustable version,the MIC29204,includes both shutdown and error flag pins,and may be pin-strapped for 5V output, or programmed from1.24 v to 26 v with the use of two externai resistors.
