DUAL CHANNEL LDO

REGULATORS WITH ENABLE

FUNCTION



DESCRIPTION

The UTC LR6401 is a low noise and high accuracy LDO voltage

regulator which has enable 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 the start function.

The UTC LR6401 comes with low design cost and outstanding

output stability and its compatibility of working with low ESR ceramic

capacitors is undoubted. Besides, and this level of stability is

ensured by the perfect transient response and PSRR derived from a

large frequency range.
