Additional preview pages of the LP2989 datasheet.

The LP2989 is a fixed-output 500 mA precision LDO regulator designed for use with ceramic output capacitors.

Output noise can be reduced to 18µV (typical) by connecting an external 10 nF capacitor to the bypass pin.

n n n n n n n n n n n Ultra low dropout voltage Guaranteed 500 mA continuous output current Very low output noise with external capacitor SO-8 surface mount package < 0.8 µA quiescent current when shutdown Low ground pin current at all loads 0.75% output voltage accuracy (“A” grade) High peak current capability (800 mA typical) Wide supply voltage range (16V max) Overtemperature/overcurrent protection.
40˚C to +125˚C junction temperature range.
