MIC2954-08YM Power Management ICs - PMIC by Microchip Technology

Improved LP2954 Low Drop-out Regulator

Status: Active
Series: MIC2954
RoHS: Compliant
View Datasheet Manufacturer Site View Pricing & Stock

The MIC2954 is a "bulletproof", efficient voltage regulator with very low dropout voltage (typically 40mV at light loads and 375mV at 250mA) and low quiescent current (120µA typical). The quiescent current of the MIC2954 increases only slightly in dropout, thus prolonging battery life. Key MIC2954 features include protection against reversed battery, fold-back current limiting, and automotive load-dump protection (60V positive transient).

The MIC2954-07/08BM is an adjustable version that includes an error flag output that warns of a low output voltage, which is often due to failing batteries on the input. This may also be used as a power-on reset. A logic-compatible shutdown input is provided which enables the regulator to be switched on and off. This part may be pin-strapped for 5V output or programmed from 1.24V to 29V with the use of two external resistors.

The MIC2954 is available in two voltage tolerances, ±0.5% maximum and ±1% maximum. Both are guaranteed for junction temperatures from -40°C to +125°C.

The MIC2954 has a very low output voltage temperature coefficient and extremely good load and line regulation (0.04% typical).
