Notes:

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, TJ(Max), the

junction-to-ambient thermal resistance, θ JA, and the ambient temperature, TA. The maximum allowable power dissipation will result in excessive die

temperature, and the regulator will go into thermal shutdown.

IC devices are inherently ESD sensitive. Handling precautions required. Human body model, 1.5kΩ in series with 100pF.

This device is not guaranteed to operate beyond its specified operating rating.

Specification for packaged product only.
