When the IN pin of the TL1963A-xx is forced below the OUT pin or the OUT pin is pulled above the IN pin, input
current typically drops to less than 2 µA. This can happen if the input of the device is connected to a discharged
(low voltage) battery and the output is held up by either a backup battery or a second regulator circuit. The state
of the SHDN pin has no effect on the reverse output current when the output is pulled above the input.
