NCP785B Datasheet (ON Semiconductor) - High PSRR Linear Regulator

NCP785B, High PSRR Linear Regulator

Pin No.

(SOT *223) Pin Name Description 1 VIN Supply Voltage Input.

Connect 1 mF capacitor from VIN to GND.

2 EN Enable pin.

Allows to turn *on/off the Regulator’s output voltage.

Pulling the EN pin low turns *off the NCP785B.

Releasing the EN pin allows the internal pull
