Note 1) Ta=25˚C except operating ambient temperature and storage temperature. Note 2) Guaranteed values if RADJ is 20kΩ or more. If RADJ is less than 20kΩ, ensure that the stated power dissipation is not exceeded. Note 3) The power dissipation is that of a package at Ta=70˚C as mounted on the standard PC board.
