2022-12-08, Microchip Technology 250 mA Low Dropout Regulator

The MIC2954 is an 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 (60V positive transient).
