8.5.1.1 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, P_D(max), and the actual dissipation, P_D, which must be less than or equal to P_D(max).

The maximum-power-dissipation limit is determined by:

Equation 6.

P_{D (m a x)} = \frac{T_{J} \max - T_{A}}{R_{θ J A}}

where:

T_Jmax is the maximum allowable junction temperature
R_θJA is the thermal resistance junction-to-ambient for the package (see the Thermal Information table)
T_A is the ambient temperature

The regulator dissipation is calculated by:

Equation 7.

P_{D} = (V_{I N} - V_{O U T}) \times I_{O U T}
