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, T_Jmax ; total thermal re-
sistance, θ_JA, and ambient temperature T_A. The maximum allowable power dissipation at any ambient tem-
perature is T_jmax-T_A / θ_JA. 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.
