DESCRIPTION
The UTC LM2940is 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 ofreducing the ground current when the differential between the inputvoltage and the output voltage outrun 3V. 

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
