Operating Temperature Range - 55 °C to + 125 °C
DC current (A) that will cause an approximate ΔT of 40 °C
DC current (A) that will cause Lo to drop approximately 20 %
The part temperature (ambient + temp rise) should not exceed
125 °C under worst case operating conditions. Circuit design,
component placement, PWB trace size and thickness, airflow
and other cooling provisions all affect the part temperature. Part
temperature should be verified in the end application.
