LDO Regulator - Very Low Dropout,
CMOS, Bias Rail
1A
NCP139
The NCP139 is a 1 A VLDO equipped with NMOS pass transistor and a separate bias supply
voltage (VBIAS).
The device provides very stable, accurate output
voltage with low noise suitable for space constrained, noise sensitive applications.
In order to optimize performance for battery operated portable applications, the NCP139 features low IQ consumption.
The WLCSP6 1.
2 mm x 0.
8 mm Chip Scale package is optimized for use in space constrained applications.
