150 mA, High Accuracy,
Very Low Dropout Bias Rail
CMOS Voltage Regulator
The NCP121 is a high accuracy 150 mA VLDO equipped with
NMOS pass transistor and a separate bias supply voltage (VBIAS). The
device provides stable, very accurate output voltage with low noise
suitable for space constrained, noise sensitive applications. In order to
optimize performance for battery operated portable applications, the
NCP121 features low IQ consumption. The XDFN6 1.2 mm x 1.2 mm
package is optimized for use in space constrained applications.
