Note:
* stand for specifications which apply over the designed operating temperature range.
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.
