FUNCTION

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.
