Note 1:

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

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

test conditions see the Electrical Characteristics.

Note2:

dissipation is exceeded, the die temperature will rise above 150°C and IC will go into thermal shutdown. For the G926 in

SOP-8 package,

θ

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, aluminum or ceramic.
