UNISONIC TECHNOLOGIES CO., LTD LR6XXYY Preliminary CMOS IC DUAL OUTPUT LOW ESR CAP. LOW-DROPOUT 600MA LINEAR REGULATOR DESCRIPTION The UTC LR6XXYY is a low noise and high accuracy LDO voltage regulator which has the soft start function. Designers can reduce power consumption more easily by applying EN function that can turn off the output of each device and control the in rush current through the soft start function. The UTC LR6XXYY comes with low design cost and outstanding output stability and its compatibility of working with low ESR ceramic capacitors is undoubted. Besides, the level of stability is ensured by the perfect transient response and PSRR derived from a large frequency range.
