NCP121: Ultra-Low Dropout High Accuracy Voltage Regulator with Bias Rail, 150 mA
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
Features- Ultra-Low Dropout of Typ. 37mV
- Fixed Output Voltage options from 0.8V to 2.1V
- 37 mV typical dropout at the full 150 mA load.
- Guaranteed Output Current from 0mA to 150mA
- 0.2% Typical Output Voltage Accuracy
