Recommended Operating Conditions indicate conditions for which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. (2) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), RθJA (junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJmax − TA)/RθJA or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4040-N, TJmax = 125°C, and the typical thermal resistance (RθJA), when board mounted, is 326°C/W for the SOT-23 package, and 180°C/W with 0.4″ lead length and 170°C/W with 0.125″ lead length for the TO-92 package and 415°C/W for the SC70 package.
