onsemi WDFN Evaluation Board Voltage Reference for NCP508SQ33T1G for Low Noise Voltage Regulator

The NCP508 is a 50 mA low noise voltage regulator, designed to exhibit fast turn on time and high ripple rejection. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, resistors for setting output voltage, current limit, and temperature limit protection circuits.

Very Low Noise at 39 Vrms without a Bypass Capacitor
High Ripple Rejection of 70 dB at 1 kHz
Low Dropout Voltage of 140 mV (typ) at 30 mA
