4. AP1117 contains an internal thermal limiting circuit that is designed to protect the regulator in the event that the maximum junction temperature
exceeded. When activated, typically at +150°C, the regulator output switches off and then back on as the die cools
.

Notes:
5. See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant junction
temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the package.
6. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference between input
and output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range.

Notes:
7. Quiescent current is defined as the minimum output current required in maintaining regulation. At 12V input/output differential the device is guaranteed
to regulate if the output current is greater than 10mA.
9. Test conditions for SOT223: Devices mounted on FR-4 substrate, single sided PC board, 2oz copper, with 5mm x 5mm thermal pad layout, no air flow.
