LR6401

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.
