Positive power supply input voltage.
Ground. This pin is internally connected to the Tab heat sink.
Regulated output voltage.
No connection (Fixed output versions).
Voltage-adjust input (Adjustable output version). Use an external voltage divider
to set the output voltage over a range of 1.25 V to 5.0 V.
