The maximum allowable power dissipation at any ambient temperature is given: PD (max) = (TJ(max) - TA) θJA. Exceeding the maximum allowable power limit will result in excessive die temperature; thus, the regulator will go into thermal shutdown. The θJA of the SPX8863 is 220oC/W mounted on a PC board. Note 2: Not apply to 1.8V version. µA mV µA V |
