PRODUCT SPECIFICATION
Electrical Characteristics
Tj = 25°C unless otherwise specified.
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
2. Line and load regulation are guaranteed up to the maximum power dissipation (18W). Power dissipation is determined by
