There is some doubt about the overcurrent protection limit in the LM76003QRNPRQ1 style book. What is the minimum overcurrent protection limit of the IC? Thank you.

1. according to the style book, personal understanding of IC's overcurrent protection limit is the value of ILS_Limit.

2, in which the following index -----3.4A is given in Electrical Characteristics

3, the graph gives the following indicators ----- 3.7A

    Hi Jeffrey,

    The EC table accounts for the characterization over multiple units plus an added guard band. On the other hand, Figure 4 is measured for one unit without a guard band. Therefore, the LS current limit in the figure will always be higher than the EC table. You should refer to the EC table for the limit.
