Pin Function
Enable: TTL/CMOS compatible input. Logic high = enable,
logic low or open = shutdown.
Bias Supply: Bias supply input for powering all internal circuitry of
the device, except the main current path.
Input Voltage: Main Power Input Supply. Supplies main current
to output device.
Ground: Package TAB is connected to Ground.
Output Voltage: Regulator Output.
No Connect
Remote Voltage Sense: Connect direct the load to improve
regulation. Connect direct to pin 6 if not used.
Adjust Input. Connect external resistor divider to program output
voltage.
