Notes:

11. 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.

12. 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.

13. The minimum Load current is defined as the minimum output current required to maintain voltage regulation. This output current can be made up of either

load current itself and/or the current delivered to the output voltage setting feedback resistors.
