NCP717
300 mA, Very-Low
Quiescent Current, IQ 25 mA,
Low Noise, Low Dropout
Regulator
The NCP717 is 300 mA LDO that provides the engineer with a very
stable, accurate voltage with very low noise suitable for space
constrained, noise sensitive applications. In order to optimize
performance for battery operated portable applications, the NCP717
employs the dynamic quiescent current adjustment for very low IQ
consumption at no−load.
