LINEAR INTEGRATED CIRCUIT
500mA LOW DROPOUT
VOLTAGE REGULATOR
DESCRIPTION
The UTC LM2937 is a positive
voltage regulator capable of supplying up to 500mA of load current.
The use of a PNP power transistor provides a low dropout
voltage characteristic.
With a load current of 500mA the 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 10mA with a full 500mA load current when the input to output
voltage differential is greater than 3V.
