9.1 Power Dissipation and Junction Temperature

Specified regulator operation is assured to a junction temperature of 125°C; the maximum junction temperature allowable to avoid damaging the device is 150°C. 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 Equation 3.

Equation 3. TPS763 equation_05_slvs181.gif

where

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

The regulator dissipation is calculating using Equation 4.

Equation 4. TPS763 equation_06_slvs181.gif

Power dissipation resulting from quiescent current is negligible.
