NCP121 Voltage Regulator - High Accuracy, Very Low Dropout, Bias Rail, CMOS 150 mA 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.
