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