Notes:
a. All test data is referenced to 25℃ ambient.
b. Operating Temperature Range-40℃ to +125℃.
c. Irms :DC current(A) that will cause an approximate△T of 40℃.
d. lsat :DC current(A) that will cause Lo to drop approximately 40%.
e. The part temperature(ambient + temp rise)should not exceed 125℃ 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.
