Electrical Characteristics
Tj = 25

C unless otherwise speci
fi
ed.
The
denotes speci
fi
cations which apply over the speci
fi
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. 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.
