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.
3.θJA : Thermal Resistance-Junction to Ambient, DF: Derating factor, Po: Power consumption
