Noise sensitive applications and precision instrumentation require very clean power supplies. The NCP752 is a 200mA LDO that provides the engineer with a very stable, accurate voltage with ultra-low noise and high Power Supply Rejection. The device doesn't require any additional noise bypass capacitor to achieve ultra-low noise levels. In order to optimize the performace for battery operated applications, the NCP752 employs the Auto Low-Power Function for Ultra-Low Quiescent Current consumption.
