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. _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.
5. _JC, “case temperature” location is at the center of the exposed metal pad on the package underside. See Tech Brief TB379.
Electrical Specifications Typical values are tested at V_IN = 5V and at an Ambient Temperature of +25°C. Unless otherwise noted.
Boldface limits apply across the operating temperature range, -40°C to +85°C and V_IN range of 4.3V to 5.5V (see Note 6).
