Enable (Input): CMOS compatible input. Logic
high = enable, logic low = shutdown. Do not
leave pin floating.
Input voltage which supplies current to the
output power device.
Ground (TAB is connected to ground on S-Pak
and TO-263).
Regulator Output.
Output voltage sense. Connect to output
voltage.
Adjustable regulator feedback input. Connect
to resistor voltage divider.
Error Flag (Output): Open collector output.
Active low indicates an output fault condition.
Exposed pad. Connect to GND.
No Connect. Not internally connected.
