onsemi NCP702SN31T1G

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.
