LM3940 - 1-A Low-Dropout Regulator

Datasheet Summary

Description

The LM3940 is a 1-A low-dropout regulator designed to provide 3.3 V from a 5-V supply.

The LM3940 is ideally suited for systems which contain both 5-V and 3.3-V logic, with prime power provided from a 5-V bus.

Features

  • 1 Input Voltage Range: 4.5 V to 5.5 V.
  • Output Voltage Specified over Temperature.
  • Excellent Load Regulation.
  • Specified 1-A Output Current.
  • Requires only One External Component.
  • Built-in Protection against Excess Temperature.
  • Short-Circuit Protected 2.
