1 UNISONIC TECHNOLOGIES CO., LTD VOLTGE REGULTOR DESCRIPTION s the UTC linear integrated LDO, the UTC shows a high current, high accuracy, low-dropout voltage which built in on/off function. The features are: low dropout voltage, very low ground current. Cause the series have been designed for high current loads, so they are also used in lower current, extremely low dropout-critical systems (in which their tiny dropout voltage and ground current values are important attributes).
