Note1: Connecting any terminal to voltages greater than (GND + 0.3V) or less than (V-IN - 0.3V) may cause destructive device latch-up.

Note 3: This parameter refers to the saturation resistance of the MOS pass tranSIstor. The minimum input-output voltage differential
can be determined by multiplying the load curront(including set resistor current, but not quiescent current) by this resistance.
