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. The family is available in a variety of packages: SC−70, SOT23 and a small, ultra thin 1.2 x 1.2 x 0.4 mm XDFN. 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.
