MIC2940A Datasheet (Micrel Semiconductor) - 1.25A Low-Dropout Voltage Regulator

MIC2940A, 1.25A Low-Dropout Voltage Regulator

The MIC2940A and MIC2941A are “bulletproof” efficient voltage regulators with very low dropout voltage (typically 40mV at light loads and 350mV at 1A), and low quiescent current (240µA typical).

The quiescent current of the MIC2940A increases only slightly in dropout, thus prolonging battery life.

MIC2940A Features

* include protection against reversed battery, fold-back current limiting, and automotive “load dump” protection (60V positive transient). The MIC2940 is available in both fixed voltage (3.3V, 5V, and 12V) and adjustable voltage configurations. The MIC2940Axx devices are three pin fixed voltage regula
