Note: 1. See thermal regulation specifications for changes in output voltage due to heating effects. Load and line
regulation are measured at a constant junction temperature by low duty cycle pulse testing.
2. Line and load regulation are guaranteed up to the maximum power dissipation. Power dissipation is
determined by input/output differential and the output current. Guaranteed maximum output power will not
be available over the full input/output voltage range.
* stand for specifications which apply over the designed operating temperature range.
