NCP115
300 mA CMOS Low Dropout
Regulator
The NCP115 is 300 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 NCP115 employs the
