junction temperature, TA is the ambient temperature, and θJA is the junction-to-ambient thermal resistance. The value of the θJA for the

WSON package is specifically dependant on the PCB trace area, trace material, and the number of layers and thermal vias. For

improved thermal resistance and power dissipation for the WSON package, refer to Application Note AN-1187 (SNOA401).
