Note1: The maximum allowable power dissipation is a function of maximum operating junction temperature, TJ
(max), the junction to ambient thermal resistance, θJA, and the ambient temperature Tamb. The maximum
allowable power dissipation at any ambient temperature is given: PD (max) = (TJ (max) - Tamb)/θJA, exceeding the
maximum allowable power limit will result in excessive die temperature; thus, the regulator will go into thermal
shutdown. The junction to ambient thermal resistance, θJA of some packages may be different, The value of θJA
depends on mounting technique.
