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

FM : SOP-8
