(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Absolute maximum input-to-output differential voltage cannot be achieved with all combinations of rated IN pin and OUT pin voltages. With the IN pin at 22 V, the OUT pin may not be pulled below 0 V. The total measured voltage from IN to OUT can not exceed ±22 V.

(1) The TPS7A4501 is tested and specified for these conditions with the ADJ pin connected to the OUT pin.
(2) Dropout voltages are limited by the minimum input voltage specification under some output voltage/load conditions.

When operating at maximum input voltage, limit the output current range. When operating at maximum output current, limit the input voltage range.
(4) To satisfy requirements for minimum input voltage, the TPS7A4501 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-µA DC load on the output.
