Quiescent Current, I_Q 12 mA,
Ultra-Low Noise, Low
Dropout Regulator
Noise sensitive RF applications such as Power Amplifiers in
satellite radios, infotainment equipment, and precision
instrumentation require very clean power supplies. The NCP752 is
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) suitable for RF applications. The device doesn’t require
any additional noise bypass capacitor to achieve ultra low noise
performance. In order to optimize performance for battery operated
portable applications, the NCP752 employs the Auto Low−Power
Function for Ultra Low Quiescent Current consumption.
