(6) Dropout voltage is the minimum input to output voltage differential needed to maintain regulation at a specified output current. In
dropout, the output voltage is equal to: V_IN – V_DROPOUT.
(7) To satisfy requirements for minimum input voltage, the TL1963A (adjustable version) is tested and specified for these conditions with an
external resistor divider (two 4.12-kΩ resistors) for an output voltage of 2.4 V. The external resistor divider adds a 300-mA DC load on
the output.
(8) GND pin current is tested with V_IN = (V_OUT(NOMINAL) + 1 V) and a current source load. The GND pin current decreases at higher input
voltages.
(9) ADJ pin bias current flows into the ADJ pin.
(10) 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 the GND pin.
