Note:
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 current. Guaranteed maximum output power will not be available over
the full input/output voltage range.
3. UZ1086 adjustable only.
4. With package soldered to 0.5 square inch copper area over backside ground plane or internal power plane,
Thermal Resistance Junction to Ambient can vary from 30°C/W to more than 50°C/W. Other mounting
techniques may provide better thermal resistance than 30°C/W.
