Fonctionnalités et applications
The MIC2954-03WS TR is a "bulletproof" efficient voltage regulator with very low dropout voltage (typically 40 mV at light loads and 375 mV at 250 mA), and low quiescent current (120 µA 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 (60 V 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 5 V output, or programmed from 1.24 V to 29 V with the use of two external resistors.
The MIC2954-03WS TR 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).
