1) The IFX1963 is tested and specified for these conditions with the ADJ pin connected to the OUT pin.
2) For IFX1963 dropout voltage will be limited by the minimum input voltage specification under some output voltage/load
conditions.
3) Operating conditions are limited by maximum junction temperature. The regulated output voltage specification will not apply
for all possible combinations of input voltage and output current. When operating at maximum input voltage, the output
current range must be limited. When operating at maximum output current, the input voltage range must be limited.
4) To satisfy requirements for minimum input voltage, the IFX1963 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 will add a 300 µA DC
load on the output.
5) Dropout voltage is the minimum input to output voltage differential needed to maintain regulation at a specified output
current. In dropout, the output voltage will be equal to: VIN – VDR
6) GND pin current is tested with VIN = VOUT,nom + 1 V and a current source load.
7) ADJ pin bias current flows into the ADJ pin.
8) EN pin current flows into the EN pin.
9) Specified by design, tested at Tamb = 25 °C
10) Not subject to production test, specified by design.
11) Reverse output current is tested with the IN pin grounded and the OUT pin forced to the rated output voltage. The reverse
output current flows into the OUT pin.
