NCP110
Linear Regulator, Low V
IN
,
Low Noise and High PSRR,
200 mA
The NCP110 is a linear regulator capable of supplying 200 mA
output current from 1.1 V input voltage. The device provides wide
output range from 0.6 V up to 4.0 V, very low noise and high PSRR.
Due to low quiescent current the NCP110 is suitable for battery
powered devices such as smartphones and tablets. 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, 0.64 mm x 0.64 mm
Chip Scale Package (CSP) and XDFN4 0.65P, 1 mm x 1 mm.
