UTCUC723
UTCUC723 is ADJUSTABLE VOLTAGE REGULATOR manufactured by Unisonic Technologies.
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 150m A. It includes a temperature-pensated reference amplifier, an error amplifier, a power series pass transistor, and a current-limiting circuit. FEATURES - Up to 150m A 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% DIP-14 BLOCK DIAGRAM UNISONIC TECHNOLOGIES CO., LTD.
