LM3940 - Voltage Regulator

Description

The Bay Linear LM3940 is a 1.25A high accuracy, low dropout voltage regulator with only 40mV at light loads and 350mV(Typ.)@ 1.0A) and low quiescent current of 240µA typical.

The LM3940 is designed for low voltage a application that requires lower dropout voltage and faster transient response.

Features

  • High output accuracy of 1% Fix Output 5.0v & 3.3V Output Current of 1.25A Low Dropout Voltage Low quiescent current Extremely Tight Load & Line Regulation Reverse-battery and “Load Dump” Protection Zero Current Shutdown Mode (5-pin version) Offer in TO-263, TO-252, TO-220, SOT-223, & New Slim LPDD Similar to industry Standard LM3940.

www.DataSheet4U.com Bay Linear Inspire the Linear Power 1.25A High Current Low Dropout Voltage Regulator for Convert 5V & 3.3V LM3940 Description The Bay Linear LM3940 is a 1.25A high accuracy, low dropout voltage regulator with only 40mV at light loads and 350mV(Typ.)@ 1.0A) and low quiescent current of 240µA typical. The LM3940 is designed for low voltage a application that requires lower dropout voltage and faster transient response. This device is an excellent choice for use in powering low voltage applications where require a lower dropout, faster transient response to regulate from +2.5V to 3.8V supplies and as a post regulator for switching supplies applications.
