Note:
θ
JC is the internal resistance from the junction to the top surface of the package. A heatsink is generally required to ensure that
the die junction temperature is maintained within the limits defined in Table 3-2, Recommended Operating Conditions, on page 15.
Note: Thermal resistance values are based on modeling only.
