power dissipation and junction temperature
Specified regulator operation is assured to a junction temperature of 125
°C; the maximum junction temperature
should be restricted to 125
°C under normal operating conditions. This restriction limits the power dissipation
the regulator can handle in any given application. To ensure the junction temperature is within acceptable limits,
calculate the maximum allowable dissipation, PD(max), and the actual dissipation, PD, which must be less than
or equal to PD(max).
The maximum-power-dissipation limit is determined using the following equation:
P
D(max) +

RqJA
Where:
TJmax is the maximum allowable junction temperature.
TA is the ambient temperature.
RθJA is the thermal resistance junction-to-ambient for the package, i.e., 32.6°C/W for the 20-terminal
PWP with no airflow.
The regulator dissipation is calculated using:

Power dissipation resulting from quiescent current is negligible. Excessive power dissipation will trigger the
thermal protection circuit.
