Part Number: LM317A
Dear all
I would like to ask a question about current limit.
The current limit is set as shown in the table above. Please tell us why the difference between TO-220, TO-252, and SOT-223 appears.
I thought that it was different due to the problem of heat capacity and checked the specifications in the table below, but when I look at this,
I can not understand why the Current Limit in TO-220 is larger than that in TO-252.
Best Regards,
Y.Ottey
