Overview

NCP4561 Ultra Low−Noise Low Dropout Voltage Regulator with 1.0 V ON/OFF Control The NCP4561 is a Low DropOut (LDO) regulator featuring excellent noise performances.

Thanks to its innovative concept, the circuit reaches an incredible 40 mVRMS noise level without an external bypass capacitor.

Housed in a small SOT−23 5 leads−like package, it represents the ideal designer’s choice when space and noise are at premium.

Key Features

  • Ultra Low.
  • Noise: 150 nV/√Hz @ 100 Hz, 40 mVRMS 100 Hz.
  • 100 kHz Typical, Iout = 60 mA, Co = 1.0 mF.
  • Fast Response Time from OFF to ON: 40 ms Typical at a 200 Hz Repetition Rate.
  • Ready for 1.0 V Platforms: ON with a 900 mV High Level.
  • Nominal Output Current of 80 mA with a 100 mA Peak Capability.
  • Typical Dropout of 90 mV @ 30 mA, 160 mV @ 80 mA.
  • Ripple Rejection: 70 dB @ 1.0 kHz.
  • 1.5% Output Precision @ 25°C.
