Note1: See Thermal Regulation specifications for changes in output vol. due to heating effects. line and
load regulation are measured at a constant junction Temp. by low duty cycle pulse testing. Load
regulation ismeasured at the output lead=1/8" from the package
Note2: Line and load Regulation are guaranteed up to the max power dissipation of 15W power dissipation
is determined by the difference between input and output and the current. Guaranteed max power
dissipation will not be available over the full input/output range
