Electrical Characteristics

The

• denotes specifications which apply over the specified operating temperature range.

Notes:

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 (18W). 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.
