Thermal Resistance (Junction-to-Case) = 5°C/W
Calculating Junction Temperature
The junction temperature can be calculated from the
equation:
where:
As an example, calculate the junction temperature for the
circuit in Figure 7 for the SO and R packages assuming a
70°C ambient temperature.
The device dissipation can be found by measuring the
supply currents, calculating the total dissipation and then
subtracting the dissipation in the load and feedback
network.
