LOW POWER CONSUMPTION

HIGH SPEED LDO REGULATOR



DESCRIPTION

The UTC LR9203 is a CMOS-based low dropout regulator with

high output voltage accuracy, low dropout, high PSRR and low

quiescent current. The devices can provide stable output voltages

is carried out internally unlike other LDOs where it is done

externally. Since the output capacitor and noise bypass capacitor

are able to be reduced, so saving the board design space.

charge stored at the output capacitor through the internal switch


