by characterization and are not production tested.

value.

10. Electromigration specification defined as lifetime average junction temperature of +110°C where max rated DC current =

lifetime average current.

12. If the current limit for in-rush current is acceptable in application, do not use this feature. Used only when large bulk capacitance

Applications must follow thermal guidelines of the package to determine worst case junction

Boldface limits apply over the operating temperature range, -40°C to +125°C.
