NCP103/D
NCP103
150 mA CMOS Low Dropout
Regulator
The NCP103 is 150 mA LDO that provides the engineer with a very
stable, accurate voltage with low noise suitable for space constrained,
noise sensitive applications. In order to optimize performance for
battery operated portable applications, the NCP103 employs the
dynamic quiescent current adjustment for very low I
Q
consumption at
no−load.
