NCP500

150 mA CMOS Low Noise

Low−Dropout Voltage

Regulator

The NCP500 series of fixed output low dropout linear regulators are

designed for portable battery powered applications which require low

noise operation, fast enable response time, and low dropout. The

device achieves its low noise performance without the need of an

external noise bypass capacitor. Each device contains a voltage

reference unit, an error amplifier, a PMOS power transistor, and

resistors for setting output voltage, and current limit and temperature

limit protection circuits.

The NCP500 has been designed to be used with low cost ceramic

capacitors and requires a minimum output capacitor of 1.0

mF.

Features

• Ultra−Low Dropout Voltage of 170 mV at 150 mA

• Fast Enable Turn−On Time of 20 msec

• Wide Operating Voltage Range of 1.8 V to 6.0 V

• Excellent Line and Load Regulation

• High Accuracy Output Voltage of 2.5%

• Enable Can Be Driven Directly by 1.0 V Logic

• Typical RMS Noise Voltage 50 mV with No Bypass Capacitor

(BW = 10 Hz to 100 kHz)

• Very Small QFN 2x2 Package

• Pb−Free Package May be Available.* The G−Suffix Denotes a

Pb−Free Lead Finish

Typical Applications

• Noise Sensitive Circuits − VCO’s, RF Stages, etc.

• SMPS Post−Regulation

• Hand−Held Instrumentation

• Camcorders and Cameras
