MIC2954-03WS Product Details
The MIC2954-03WS 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 MIC2954-03WS increases only slightly in dropout, thus prolonging battery life. Key MIC2954-03WS 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 MIC2954-03WS 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 MIC2954-03WS has a very low output voltage temperature coefficient and extremely good load and line regulation (0.04% typical).
