Pinout
1. IN (Pin 1): Input voltage pin. Connect to the input supply voltage.
2. NC (Pin 2, 3, 6): No internal connection. Can be left floating or tied to ground.
3. EN (Pin 4): Enable pin. A high voltage enables the regulator; a low voltage disables it.
4. NR/SS (Pin 5): Noise reduction/soft start pin. Connect a capacitor to this pin to reduce output noise or control startup characteristics.
5. FB (Pin 7): Feedback pin. Connects to the resistor divider to set the output voltage.
6. OUT (Pin 8): Output voltage pin. Connect to the load.
Additionally, the package's thermal pad should be connected to the ground plane for optimal thermal performance and should be considered part of the ground connection.
