(1)
If Sense(–) is not used, pin 5 must be connected to pin 4 for optimum output voltage accuracy.
(2)
The Remote On/Off input has an internal pull-up and may be controlled with an open collector (or open drain) interface. An open circuit
correlates to a logic high. Consult the application notes for interface considerations.
