The NCV8705 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 NCV8705 uses an
innovative Adaptive Ground Current circuit to ensure ultra low
ground current during light load conditions.
