Note 1:

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.

Note 2:

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.
