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 �F.
Features Ultra−Low Dropout V oltage of 170 mV at 150 mA Fast Enable Turn−On Time of 20 �sec 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 V oltage 50 �V with No Bypass Capacitor
