NCP148 Datasheet, PDF (1/12 Pages) ON Semiconductor – Ultra-Low Noise High PSRR LDO Regulator Analog Circuits

NCP148
450 mA, Ultra-Low Noise
and High PSRR LDO
Regulator for RF and
Analog Circuits
The NCP148 is a linear regulator capable of supplying 450 mA
output current. Designed to meet the requirements of RF and analog
circuits, the NCP148 device provides low noise, high PSRR, low
quiescent current, and very good load/line transients. The NCP148
offers soft−start function with optimized slew rate control to use in
camera module. The device is designed to work with a 1 mF input and a
1 mF output ceramic capacitor. It is available in ultra−small 0.35P,
0.65 mm x 0.65 mm Chip Scale Package (CSP).
