Microchip MIC29201-3.3WT

正26V400mA

Overview

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 (140µA 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 3-pin fixed-voltage regulators available in 3.3V, 4.85V, 5V, and 12V outputs. The MIC29201-3.3WT is a fixed regulator offering a logic-compatible 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 that 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.
