1.0A LOW DROPOUT LINEAR

REGULATOR WITH OUTPUT

VOLTAGE SETTING OPTIONS



DESCRIPTION

The UTC LR18943A is a typical LDO that features output

voltage setting options, very low dropout voltage as low as 0.3V

at output current 1.0A, an enable input and the soft-start reduces

inrush current of the load capacitors and minimizes stress on the

input power source during start-up. An enable pin to further

reduce power dissipation while shutdown..

The UTC LR18943A is stable with any type of output

capacitor of 10µF or more. A precision reference and feedback

control deliver 2% accuracy.
