Note 1:

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 allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.

Note 2:

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

Note 3:

IC devices are inherently ESD sensitive. Handling precautions required. Human body model rating: 1.5K in series with 100pF.

Note 4:

Note 5:

Guaranteed by design
