The LM2937 is a positive voltage regulator capable of supplying
up to 500 mA of load current. The use of a PNP power
transistor provides a low dropout voltage characteristic. With
a load current of 500 mAthe minimum input to output voltage
differential required for the output to remain in regulation is
typically 0.5V (1V guaranteed maximum over the full operating
temperature range). Special circuitry has been incorporated
to minimize the quiescent current to typically only
10 mA with a full 500 mA load current when the input to
output voltage differential is greater than 3V.
