Notes:
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 maxim
um power dissipation of 30 W.
Power dissipation is determined by the input/output differential voltage and the output curren
t. 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. The denotes the specifications which apply over the full operating temperature range.
