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.
