Microchip MIC2920A-3.3WS-TR, 1 Low Dropout Voltage, Voltage Regulator 400mA, 3.3 V 3-Pin, SOT-223

The Microchip Technology MIC2920A series bulletproof LDO regulator is a new age device with a low dropout voltage and quiescent current. The quiescent current increases slightly in dropout, prolonging battery life. It includes protection against reversed battery, folds back current limiting, and automotive load dump protection.
