Overview

The MIC2940A and MIC2941A are “bulletproof" efficient voltage regulators with very low dropout voltage (typically 40 mV at light loads and 350 mV at 1A), and low quiescent current (240 μA typical). The quiescent current of the MIC2940A increases only slightly in dropout, thus prolonging battery life. Key MIC2940A features include protection against reversed battery, fold-back current-limiting, and automotive “load dump" protection (60V positive transient). The MIC2940A is available in both fixed voltage (3.3V, 5V, and 12V) and adjustable voltage configurations. The MIC2940A-xx devices are three pin, fixed-voltage regulators. A logic-compatible shutdown input is provided on the adjustable MIC2941A, which enables the regulator to be switched on and off.
