ELECTRICAL CHARACTERISTICS

Typicals and limits appearing in normal type apply for Tj= +25°C.

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 aremeasured 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 byinput/output differential and the output currrent.

Guaranteed maximum output power will not be available over the full input/output voltage range.
