600mA LOW DROPOUT LINEAR

REGULATOR



DESCRIPTION

The UTC LR1148 belonged to low-noise, low-dropout, linear

regulators operate from 2.3V to 6V input and are guaranteed to

deliver 600mA. Wide range of preset output voltage options are

available. Built-in low on-resistance transistor provides low dropout

voltage and large output current. The UTC LR1148 is designed and

optimized for battery-powered systems to work with low noise.

The UTC LR1148 consumes less than 0.01μA in shutdown

mode. Other features include ultra low dropout voltage, current

limiting protection, thermal shutdown protection and high ripple

rejection ratio.
