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:
1. 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.
2. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications
Typical Values Are Tested at V_IN = 5V and the Ambient Temperature at +25°C. All Maximum and Minimum
Values Are Guaranteed Under the Recommended Operating Supply Voltage Range and Ambient Temperature
Range, Unless Otherwise Noted.
