UNISONIC TECHNOLOGIES CO., LTD 78RXX LINEAR INTEGRATED CIRCUIT LOW DROPOUT VOLTAGE REGULATOR 1 As the UTC linear integrated LDO, the UTC 78RXX shows a high current, high accuracy, and specially low-dropout voltage. The features are: maximum 500mV 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).
