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 3W. Power dissipation is
determined by the difference in input and output and the output current. Guaranteed maximum power dissipation will
not be available over the full input/output range.
