Note 1: See thermal regulation specification 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 input / output voltage difference and the output current. Guaranteed maximum power

dissipation will not be available over the full input / output voltage range.

Note 3: Quiescent current is defined as the minimum output current required to maintain the regulation.
