SOURCE

Input pin.

This pin is connected to a pull-down resistor internally, so that even when input wiring is

open-circuited, output can never be turned on inadvertently.

Output pin.

The current limit for output current is 5 A (typ.) when excessive current flow into a device because

of in-rush current and short load of a lamp.

Ground pin.
