THERMAL INFORMATION
Comparing P
D(total)
with P
D(max)
reveals that the power dissipation in this example does not exceed the maximum
limit. When it does, one of two corrective actions can be taken. The power-dissipation limit can be raised by increasing
either the airflow or the heat-sink area. Alternatively, the internal power dissipation of the regulator can be lowered
by reducing either the input voltage or the load current. In either case, the above calculations should be repeated with
the new system parameters.
