General Description

Pin No.

XDFN Pin No.

SC−70 Pin No.

Overview

NCP4589 300 mA, Tri-Mode, LDO Linear Voltage Regulator The NCP4589 is a CMOS 300 mA LDO which switches to a low power mode under light current loads.

The device automatically switches back to a fast response mode as the output load increases above 3 mA (typ.).

The device can be placed in permanent fast mode through a mode select pin.

Key Features

  • Operating Input Voltage Range: 1.4 V to 5.25 V.
  • Output Voltage Range: 0.8 to 4.0 V (available in 0.1 V steps).
  • Supply Current: Low Power Mode.
  • 1.0 mA at VOUT < 1.85 V Fast Mode.
  • 55 mA Standby Mode.
  • 0.1 mA.
  • Dropout Voltage: 230 mV Typ. at IOUT = 300 mA, VOUT = 2.8 V.
  • ±1% Output Voltage Accuracy (VOUT > 2 V, TJ = 25 °C).
  • High PSRR: 70 dB at 1 kHz (Fast response mode).
  • Line Regulation 0.02%/V Typ.
  • C.
