NCP139AFCT105T2G ON Semiconductor

LDO Regulator - Very Low Dropout, CMOS, Bias Rail 1 A NCP139 The NCP139 is a 1 A VLDO equipped with NMOS pass transistor and a separate bias supply voltage (V ). The device provides very BIAS www.onsemi.com stable, accurate output voltage with low noise suitable for space T constrained, noise sensitive applications. In order to optimize performance for battery operated portable applications, the NCP139 MARKING features low I consumption. The WLCSP6 1.2 mm x 0.8 mm Chip DIAGRAM Q Scale package is optimized for use in space constrained applications.
