The MIC2920A family 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). 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 used as a power-on reset signal.Alogic-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.
