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 different packages may be different, and the he
value of θJA depends on mounting technique.
