Notes:
1. See thermal regulation sperifications for changes in output voltage due to heation effects. Load and line regulation are measured
at a constant junction temperature by low duty cycle pulse testing.
2. 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.
