The NCV8189 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 NCV8189 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 NCV8189 is designed to work with a 4.7 F input and output
ceramic capacitor. It is available in industry standard DFNW8 0.65P,
3 mm x 3 mm and WDFNW6 0.65P, 2 mm x 2 mm.
