NOTES:
4. θ JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
5. θ JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
6. For θ JC , the "case temp" location is the center of the exposed metal pad on the package underside.
7. For θ JC , the “case temp” location is taken at the package top center.
Electrical Specifications Operating Conditions: V IN = 12V, PVCC shorted with VCC5, T A = +25°C. Boldface limits apply over the
operating temperature range, -40°C to +85°C.
