Pin Function
Output pin and overvoltage protection (Output): Connect to the output ca-
pacitor and LEDs.
Supply (Input): Input voltage.
Enable (Input): Logic high enables regulator. Logic low shuts down regula-
tor.
No connect (no internal connection to die).
Feedback (Input): Output voltage sense node. Connect the cathode of the
LED to this pin. A resistor from this pin to ground sets the LED current.
Switch node (Input): Internal power transistor collector.
Ground (Return): Ground.
Ground (Return): Exposed backside pad.
