ON NCP4589DSQ33T1G

正5.25V300mA

Overview

The NCP4589DSQ33T1G 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.

• 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 μA at VOUT < 1.85 V Fast Mode – 55 μA Standby Mode – 0.1 μA• 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.• Current Fold Back Protection• Stable with Ceramic Capacitors• Available in 1.2x1.2 XDFN, SC−70 and SOT23 Package• These are Pb−free Devices
