... For additional thermal resistance information see table in the Applications section. Note 3: Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output due to heating effects can be computed by multiplying the internal dissipation by the thermal resistance. ...

... This presumes that the ambient air temperature is almost the same as the surface temperature; if the air temperature were much higher or lower than the surface temperature, the actual temperature of the LM35 die would interme- diate temperature between the surface temperature and the air temperature. This is expecially true for the TO-92 plastic ...
