Ultra-Low
Noise, LDO Voltage Regulator
The NCV8703 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 NCV8703 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.
Power supply ground. Connected to the die through the lead frame. Soldered to the
copper plane allows for effective heat dissipation.
Enable pin. 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. A small capacitor is needed from this pin to ground to assure stability.
