Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which
the device is functional, but do not guarantee speci?c performance limits. For guaranteed speci?cation and test conditions, see the “Electrical
Characteristics” . The guaranteed speci?cations apply only for the test conditions listed. Some performance characteristics may degrade when
the device is not operated under the listed test conditions.
The maximum power dissipation must be derated at elevated temperatures and is dictated by T JMAX (maximum junction temperature), θ JA
(junction to ambient thermal resistance), and T A (ambient temperature). The maximum allowable power dissipation at any temperature is PD-
MAX = (T JMAX – T A )/ θ JA or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4040 and LM4041,
T JMAX = 125°C, and the typical thermal resistance ( θ JA ), when board mounted, is 326°C/W for the SOT-23 package.
The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin. The machine model is a 200pF capacitor
discharged directly into each pin.
