LDO Regulator, 1 A, Ultra-Low Dropout, with Bias Rail

Active

Overview

NCP139 is a 1 A LDO equipped with NMOS passtransistor and a separate bias supply voltage (VBIAS). The deviceprovides very stable, accurate output voltage with low noise suitablefor space constrained, noise sensitive applications. In order tooptimize performance for battery operated portable applications, theNCP139 features low IQ consumption. The WLCSP6 1.2 mm x 0.8 mmpackage is optimized for use in space constrained applications.
