4. See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant
5. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference between
6. Test conditions for TO220-3L, TO252-3L and TO263-3L: Devices mounted on FR-4 substrate, single sided PC board, 2oz copper, with minimum
junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the package.
