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
Brief
TB379.
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.

NOTES:
8. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
9. Dropout is defined by the difference in supply V
IN
and V
OUT
when the supply produces a 2% drop in V
OUT
from its nominal value.
10. Minimum cap of 10µF X5R/X7R on V
IN
and V
OUT
required for stability.
11. If the current limit for in-rush current is acceptable in application, do not use this feature. Used only when large bulk capacitance required on V
