5. Junction temperature is a function of 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.

6. See Section 5.1 from more details on thermal design considerations.

7. TJ = Junction Temperature

TA = Ambient Temperature
