NCV8702
200 mA, Ultra-Low Quiescent
Current, Ultra-Low Noise, LDO
Linear Voltage Regulator
The NCV8702 is a low noise, low power consumption and low
dropout Linear Voltage Regulator. With its excellent noise and PSRR
specifications, the device is ideal for use in products utilizing RF
receivers, imaging sensors, audio processors or any component
requiring an extremely clean power supply. The NCV8702 uses an
innovative Adaptive Ground Current circuit to ensure ultra low
ground current during light load conditions.

Description
Regulated output voltage pin. A small 1
mF
ceramic capacitor is needed from this pin to ground
to assure stability.
Not connected. This pin can be tied to ground to improve thermal dissipation.
Power supply ground.
Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator into
shutdown mode.
Not connected. This pin can be tied to ground to improve thermal dissipation.
Input pin. It is recommended to connect a 1
mF
ceramic capacitor close to the device pin.
