Notes:

5. ZLDO1117 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.

6. Test condition for SOT223: TA = +27°C, no air flow, device mounted on 2”X2” polyimide PCB, 2 oz copper, 5.6mmX5.6mm pad.

7. Test condition for TO252: TA = +27°C, no air flow, device mounted on 2”X2” polyimide PCB, 1 oz copper, 2cmX2cm pad.

8. Ensures correct operation without entering dropout. Device will continue to operate below this minimum input voltage under dropout conditions.

Notes:

9. 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.

10. 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.
