300 mA CMOS Low Dropout
Regulator
The NCP146 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 NCP146 employs the
dynamic quiescent current adjustment for very low I_Q consumption at
no−load.
