Product Overview
NCP702: LDO Regulator, 200 mA, Ultra-Low Dropout, Ultra-Low Iq, High PSRR,
Ultra-Low Noise
For complete documentation, see the data sheet.
Noise sensitive applications such as Phase Locked Loops, Oscillators, Frequency Synthesizers, Low Noise Amplifiers and other
Precision Instrumentation require very clean power supplies. The NCP702 is a 200 mA LDO that provides the engineer with a very
stable, accurate voltage with ultra-low noise and very high Power Supply Rejection Ratio (PSRR), making it suitable for RF
applications. The device doesn't require an additional noise bypass capacitor to achieve ultra-low noise performance. In order to
optimize performance for battery operated portable applications, the NCP702 employs an Adaptive Ground Current feature for ultra-
low ground current consumption during light-load conditions.
