Thermal Shutdown Hysteresis
Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Con-
ditions 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: The maximum power dissipation is a function of the maximum junction temperature, TJmax ; total thermal re-
sistance, θJA, and ambient temperature TA. The maximum allowable power dissipation at any ambient tem-
perature is Tjmax-TA / θJA. If 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.
