The

cations which apply over the speci

ed 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 currrent. Guaranteed maximum output power will not be available over the full input/
output voltage range.
3. FAN1587A only.
4. FAN1587A-1.5 only.
5. FAN1587A-3.3 only.
6. Output current must be limited to meet the absolute maximum ratings of the part.
