1. Line and load regulation are measured at a constant junction temperature using a low duty cycle pulse technique.
Although power dissipation is internally limited, regulation is guaranteed up to the maximum power dissipation of
26W. Power dissipation is determined by the input/output differential voltage and output current. Guaranteed
maximum power dissipation will not be available over the full input/output voltage range.
2. Guaranteed by design, characterization or correlation to other tested parameters.
3. Specifications apply over the operating temperature range.
