TL431: I need to know TL431ILPMR pin assign

h.sasai

Part Number: TL431

I would like to know the pinout of the TL431ILPMR. Checking the datasheet, it looks like the placement is reversed left to right in the table on page 4 and the diagram on pages 80-81. The datasheet I referred to is this: https://www.ti.com/jp/lit/gpn/tl431 I am in a hurry with my design and would like to know as soon as possible.

Cathode is pin 1. Perhaps I don't follow your question.
