Note 1:

Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Conditions are

conditions under which the device functions but the specifications might not be guaranteed. For guaranteed specifications

and test conditions see the Electrical Characteristics.

Note2:

this dissipation is exceeded, the die temperature will rise above 150°C and IC will go into thermal shutdown.

Note3:

Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.

Note4:

The type of output capacitor should be tantalum or aluminum.
