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:
The maximum power dissipation is a function of the maximum junction temperature, TJmax ; total thermal resistance, θJA,
and ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is Tjmax-TA / θJA. If this
dissipation is exceeded, the die temperature will rise above 150°C and IC will go into thermal shutdown. For the G9131 in
SOT-23 package,
θ
JA is 276°C/W and in the SOT-89 package is 173°C/W (See Recommended Minimum Footprint). The
safe operation in SOT-89 & SOT-23 package, it can see “Typical Performance Characteristics” (Safe Operating Area).
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.
