BOOSTING VOLTAGE
REGULATORS
DESCRIPTION
The UTC UC621XX is a positive output voltage
regulator that can supply up to 1A of output current using an external
transistor. Low power and high accuracy are achieved through CMOS process and metal fuses trimming technologies. The series consists of a high precision voltage reference, an error correction circuit and a short-circuit protected output driver. In stand-by mode, supply current can be dramatically cut. Since the input-output voltage differential is small, loss control efficiency is good. The UTC UC621XX is particularly suited for use with battery operated portable products, and products where supply current regulation is required.
