NCP120/D
NCP120
150mA, Very Low Dropout
Bias Rail CMOS Voltage
Regulator
The NCP120 is a 150 mA VLDO equipped with NMOS pass
transistor and a separate bias supply voltage (V
BIAS
). The device
provides very stable, accurate output voltage with low noise suitable
for space constrained, noise sensitive applications. In order to
optimize performance for battery operated portable applications, the
NCP120 features low I
Q
consumption. The XDFN6 1.2 mm x 1.2 mm
package is optimized for use in space constrained applications.
