Notes:

3. 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.

4. 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 and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range.

5. Test conditions for TO220-3L, TO252-3L and TO263-3L: Devices mounted on FR-4 substrate, single sided PC board, 2oz copper, with minimum

recommended pay layout, no air flow. The case point of θJC is located on the thermal tab.
