Description
AI
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.
