3 / 13 page PRODUCT SPECIFICATION FAN1585A REV. 1.1.6 7/8/05 3 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 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 currrent. Guaranteed maximum output power will not be available over the full input/output voltage range. 3. FAN1585A only. 4. FAN1585A-1.5 only. 5. FAN1585A-1.8 only. Parameter Conditions Min. Typ.
