Package: MSOP-8
PinNameFunctionSource
1VOUT: Regulated output voltage. Bypass VOUT to GND with a capacitor of 2.2µF or larger.
2FB: Adjustable input. External resistor divider sets the output voltage.
3NC: No Connect. Do not connect this pin.
4GND: Ground.
5EN: Enable pin. Drive EN to 2V or more above or below ground to enable the regulator; or drive EN low to disable. For auto-start, connect EN to VIN.
6SS: Soft-start pin.
7NC: No Connect. Do not connect this pin.
8VIN: Regulator input supply. Bypass VIN to GND with a capacitor of 2.2µF or larger.
9EPAD: Exposed pad. The exposed pad on the bottom of the package enhances heat dissipation and is electrically connected to VIN inside the package. Connect to the VIN layer on the PCB for proper operation.
