NCP140 LDO Voltage Regulator - Capacitor Free, Low Noise 150 mA The NCP140 is a 150 mA very low dropout regulator which offers www.onsemi.com excellent voltage accuracy and clean output voltage for power T sensitive application. The NCP140 is very suitable for battery powered application due to very low quiescent current and virtually MARKING zero current at disable mode. This device is stable with or without DIAGRAMS output capacitors and allows minimize footprint and BOM. The XDFN4 package is optimized for use in space constrained XM XDFN4, 0.8x0.8 applications.
