NCP4589

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 = 2.8 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 Typical Applications Battery Powered Equipments Portable Communication Equipments Cameras, Image Sensors and Camcorders VIN C1 1m NCP4589 VIN VOUT CE AE GND VOUT C2 1m http://onsemi.com MARKING DIAGRAMS SC−70 CASE 419A XXX XMM XDFN6 CASE 711AA XX MM SOT−23−5 CASE 1212 XXXMM 1 XXXX = Specific Device Code MM = Date Code ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 27 of this data sheet.
