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. θJA 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.
5. θJC, “case temperature” location is at the center of the exposed metal pad on the package underside.
Electrical Specifications
Unless otherwise noted, all parameter limits are established over the recommended
operating conditions and the typical specification are measured at the following conditions
unless otherwise noted: TA = -40°C to +85°C, VIN = 3.6V, EN = VDD. Typical values are at
TA = +25°C. Boldface limits apply over the operating temperature range, -40°C to
+85°C.
