3 / 8 page FAN1112 PRODUCT SPECIFICATION REV. 1.0.1 9/27/01 3 Electrical Characteristics Operating Conditions: VIN ≤ 7V, 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 (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. 3. Output current must be limited to meet the absolute maximum ratings of the part. Parameter Conditions Min. Typ. Max.
