(1) Power dissipation is limited to 2W for device production testing purposes. The power dissipation is potentially higher during normal operation. See the Thermal Performance section for more information on how much power the device can dissipate while maintaining a junction temperature below 150℃.
(2) Specified by design.
(3) For the adjustable output this is tested in unity gain and resistor current is not included.
