LINEAR INTEGRATED CIRCUIT  
1A LOW-DROPOUT POSITIVE  
VOLTAGE REGULATOR

DESCRIPTION  
The UTC LM2940 is a low dropout regulator designed to  
provide output current up to 1A with a typically 500mV dropout  
Voltage and a maximum of 1V. It is capable of reducing the  
ground current when the differential between the input voltage  
and the output voltage outrun 3V.  
UTC LM2940 offers low quiescent current (typically 30mA at  
1A and an input-output differential of 5V). Higher quiescent  
currents only exist when the regulator is in the dropout mode  
(VIN-VOUT3V).  
FEATURES  
* 500mV Typically Dropout at 1A  
* Output Current in Excess of 1A  
* Low Quiescent Current  
* Reversed-Battery Protection  
* Current Limit and Thermal Shutdown.  
* Mirror Image Insertion Protection
