Note 9:
ADJ pin bias current flows into the ADJ pin.

N pin current flows into the

N pin.
Note 11:
Reverse output current is tested with the IN pin grounded and the
OUT pin forced to the rated output voltage. This current flows into the OUT
pin and out of the GND pin.
Note 12:
For the LT1965, the minimum input voltage specification limits
the dropout voltage under some output voltage/load conditions.
Note 13:
This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed 125°C when overtemperature is active.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
