Enable (Input): TTL/CMOS compatible input. Logic high =
enable; logic low or open = shutdown.
Unregulated Input: +16V maximum supply.
Ground: Ground pin and TAB are internally connected.
Regulator Output.
Error Flag (Output): Open-collector output. Active low
indicates an output fault condition.
Adjustable Regulator Feedback Input: Connect to the
resistor voltage divider that is placed from OUT to GND in
order to set the output voltage.
