NCP752ASN28T1G產(chǎn)品概述
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.
