LINEAR INTEGRATED CIRCUIT
ADJUSTABLE VOLTAGE
REGULATOR
DESCRIPTION
The UTC UC723 is a silicon monolithic integrated circuit, designed for service as voltage
regulator at output voltages, ranging from 2V to 37V at current up to 150mA. It includes a temperature-compensated reference amplifier, an error amplifier, a power series pass
transistor, and a current-limiting circuit.
FEATURES
*Up to 150mA output current *Adjustable output voltage (from 2V to 37V) *Positive and negative voltage regulation *Regulation in excess of 10A with suitable pass
transistors *Input and output short-circuit protection *Load and line regulation< 0.03%
