General Description

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.

Overview

MIC2940A/2941A Micrel MIC2940A/2941A 1.25A Low-Dropout Voltage Regulator Preliminary Information.

Key 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 regulators. A logiccompatible shutdown input is provided on the adjustable MIC2941A, which enables the regulator to be switched on and off. Features.
  • High output voltage accuracy.
  • Guarant.
