PRODUCTION DATA
To provide reliable operation, make sure worst-case junction temperature does not exceed 125°C. This restriction limits the power dissipation the regulator handles in any given application. To make sure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation, PD(max), and the actual dissipation, PD. Make sure PD is less than or equal to PD(max).
Equation 11 determines the maximum-power-dissipation limit:
where:
Equation 12 calculates the regulator dissipation:
