Junction temperature is a function of die size, on-chip power dissipation, package thermal
resistance, mounting site (board) temperature, ambient temperature, air flow, power
dissipation of other components on the board, and board thermal resistance.
See Section 8.1, “Thermal Design Considerations,” for more detail on thermal design
considerations.
