Good day. I am posting this inquiry on behalf of the customer.
Regarding the part number LM431ACZ/NOPB, TO-92 package.
In the datasheet Pin Configuration (Pin orientation) and Functions referred in page number 3 are different from the assembly dimension on page 34
pin sequence conflict on pages 34 and 3.
Ex it is shown as 2,3,1 on page 3 but on page 34 it shows 3,2,1
Please help to advise. Thank you for extending your support.
