Description

NCP121 is a High Accuracy 150 mA VLDO equipped with NMOS passtransistor and a separate bias supply voltage (VBIAS). The deviceprovides stable, very accurate output voltage with low noise suitablefor space constrained, noise sensitive applications. In order tooptimize performance for battery operated portable applications, theNCP121 features low IQ consumption. The XDFN6 1.2 mm x 1.2 mmpackage is optimized for use in space constrained applications
