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 V_OUT < 1.85 V
Fast Mode – 55 mA
Standby Mode – 0.1 mA
• Dropout Voltage: 230 mV Typ. at I_OUT = 300 mA, V_OUT = 2.8 V
• ±1% Output Voltage Accuracy (V_OUT > 2 V, T_J = 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
