Function

Switch pin. This is the drain of the internal power switch. For

minimum EMI, minimize the trace area connected to this pin.

Ground pin. Connect pin 2 to ground.

LED (cathode) connection pin.

Shutdown pin.

Input supply pin. This pin should be bypassed with a

capacitor to ground. A 1µF capacitor mounted close to the

pin is recommended.
