Note :

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

thermal shutdown.

2.TJ: Junction Temperature Calculation:

TJ = TA+ (PD × θJA)

The

θ

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

ambient airflow.
