Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical

specifications do not apply when operating the device outside of its operating ratings. 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, TA.

The maximum allowable power dissipation at any ambient temperature is calculated using:

PD(max) = (T_J(max)– T_A) ÷ θ_JA. Exceeding the maximum allowable power dissipation will result in

excessive die temperature, and the regulator will go into thermal shutdown.
