Parameter
Parameter
Unregulated voltage input. An internal regulator powers
the internal logic.
The feedback terminal of the regulation loop. The output
is connected directly to this terminal for 5.1V operation;
it is connected via a divider for higher voltages.
A series RC network connected between this terminal
and ground determines the regulation loop gain
characteristics.
