Microchip MIC2920A-5.0BS

Позитив26V400 мА

Overview

The MIC2920A-5.0BS 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-5.0BS increases only slightly in dropout, prolonging battery life. Key MIC2920A-5.0BS 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 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.
