Description
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).
Features
- include protection against reversed battery, foldback 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 prog.
