CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact
product reliability and result in failures not covered by warranty.
NOTES:
4. All voltages are with respect to GND.
5. 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 Brief TB379.
6. For θ JC , the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications
Operating Conditions: VIN = 12V, PVCC shorted with VCC5, T A = +25°C. Boldface limits
apply over the operating temperature range, -40°C to +85°C.
