200 mA, Ultra-Low Quiescent
Current, Ultra-Low Noise, LDO
Linear Voltage Regulator
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.
