NCP705: Voltage Regulator, LDO, Ultra Low Noise, Ultra Low Iq, 500 mA

Description: Noise sensitive RF applications such as Power Ampl...
  • Noise sensitive RF applications such as Power Amplifiers in satellite radios, infotainment equipment, and precision instrumentation require very clean power supplies. The NCP705 is a 500 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 NCP705 employs dynamic Iq management for ultra-low quiescent current consumption at light-load conditions and great dynamic performance.
