Bay Linear  
Inspire the Linear Power  
1.25A High Current Low Dropout  
LM2940/2941  
Voltage Regulator Adjustable  
Description  
The Bay Linear LM2940 & LM2941 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.

High output accuracy of 1%  
Output Adjustable from 1.24V to 26V  
Output Current of 1.25A  
Low Dropout Voltage  
Low quiescent current  
The LM2940/41 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.  
Extremely Tight Load & Line Regulation  
Reverse-battery and “Load Dump” Protection  
Zero Current Shutdown Mode (5-pin version)  
Offer in TO-263, TO-220, SOT-223, & New Slim

Similar to industry Standard MIC2940LM2941  
The LM2940/41 offers full protection against over-current faults,  
reversed input polarity, reversed load insertion, and positive and  
negative transient voltage. On-Chip trimming adjusts the reference  
voltage to 1%. The LM2940-xx devices are in 3 pin fixed voltage  
regulators. The LM2941 include an Enable pin in the 5 pin
