NCP137/D
NCP137
700 mA, Very Low Dropout
Bias Rail CMOS Voltage
Regulator
The NCP137 is a 700 mA 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
NCP137 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.
