NCP4587/D
NCP4587
150 mA, Tri-Mode, LDO
Linear Voltage Regulator
The NCP4587 is a CMOS 150 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.) or it 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 an ultra thin (0.4 mm) small 1.2 x 1.2 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
Fast Mode – 55 mA
Standby Mode – 0.1 mA
• Very Low Dropout: 120 mV Typ. at 150 mA (V
out
> 2.6 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 1.2 x 1.2 XDFN, SC−70 and SOT23 Package
• These are Pb−Free Devices
Typical Applications
• Battery Powered Equipments
• Portable Communication Equipments
• Cameras, Image Sensors and Camcorders
