Description
The MIC2954 is a "bulletproof" efficient voltage regulator with very low dropout voltage (typically 40mV @ light loads and 375mV @ 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.
