Power Dissipation

To provide reliable operation, worst-case junction temperature must not exceed 125°C. This restriction limits the power dissipation the regulator can handle 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, which must be less than or equal to PD(max).

The maximum-power-dissipation limit is determined by:

Equation 6. PDmax= TJmax- TARθJA

where:

  • TJmax is the maximum allowable junction temperature
  • RθJA is the thermal resistance junction-to-ambient for the package (see the Thermal Information table)
  • TA is the ambient temperature

The regulator dissipation is calculated by:

Equation 7. PD=(VIN- VOUT)×IOUT
