Note:1.Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into

Thermal shutdown.

2.TJ: Junction Temperature Calculation TJ = TA + ( PD x θJA )

The θJA numbers are guidelines for the thermal performance of the device/PC-board system. All of the above assume no

Ambient airflow.
