The NCP189 is a 0.5 A LDO, next generation of high PSRR, low

noise and low dropout regulators with Power Good open collector

output. Designed to meet the requirements of RF and sensitive analog

circuits, the NCP189 device provides low noise, high PSRR and low

quiescent current while offering the ability to regulate output voltages

down to 0.6 V. The device also offers excellent load / line transients.

The NCP189 is designed to work with a 4.7 F input and output

ceramic capacitor. It is available in industry standard WDFNW6

0.65P, 2 mm x 2 mm.
