NCP139
1 A, Very Low Dropout Bias
Rail CMOS Voltage
Regulator
The NCP139 is a 1 A VLDO equipped with NMOS pass transistor
and a separate bias supply voltage (V
BIAS
). 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 I
Q
consumption. The WLCSP6 1.2 mm x 0.8 mm Chip
Scale package is optimized for use in space constrained applications.
