11.3 Thermal Considerations

The maximum IC junction temperature must be restricted to 125°C under normal operating conditions. To calculate the maximum allowable dissipation, PD(max) for a given output current and ambient temperature, use Equation 5 as a guideline:

Equation 5. GUID-1403EDB7-DCDD-4B00-BAA9-C573E2787098-low.gif

Where,

PD(max) = maximum allowable power dissipation

TJ(max) = maximum allowable junction temperature

TA = ambient temperature for the device

θJA = junction to air thermal impedance. See the Thermal Information section.
