The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction to ambient thermal
resistance,
θJA, and the ambient temperature, TA. Exceeding the maximum allowable power dissipation will cause excessive die
temperature and the regulator will go into thermal shutdown.
