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, T A . The maximum allowable power
dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
This device is not guaranteed to operate beyond its specified operating rating.
IC devices are inherently ESD sensitive. Handling precautions required. Human body model rating: 1.5K in series with 100pF.
