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. 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. For θ JC , the “case temp” location is the center of the exposed metal pad on the package underside.
6. ABS max voltage rating is defined as the voltage applied for a lifetime average duty cycle above 6V of 1%.
7. Electromigration specification defined as lifetime average junction temperature of +110°C where max rated DC current = lifetime average current.
Electrical Specifications Unless otherwise noted, all parameters are established over the following specified conditions:
V IN = V OUT + 0.4V, V OUT = 1.8V, C IN = C OUT = 10 μ F, T J = +25 ° C, I LOAD = 0A. Applications must follow thermal guidelines of the package to
determine worst case junction temperature. Please refer to “Functional Description” on page 12 and Tech Brief TB379 .
Boldface limits apply over the operating temperature range, -40°C to +125°C. Pulse load techniques used by ATE to ensure T J = T A defines
established limits.
