Maxim MIC2940A-5.0WU

Позитив26V1.25A

Overview

The MIC2940A-5.0WU 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-5.0WU increases only slightly in dropout, thus prolonging battery life. Key MIC2940A-5.0WU 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 MIC2940A-xx devices are 3-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.
