(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.
