LM317: PCN# 20250618000.1 clarification

Part Number: LM317


Tool/software:

Hello, 

Following the PCN# 20250618000.1, I have a question about the pinout in SOT223 package.

In top view i can see a difference in the pinout if i do a rotation with the old drawing to be like the new one.

Could you confirm if there is a mistake or not ? could you confirm that there is no inversion between Adjust pin and Input pin with the new silicon?

I think it is a mistake because in the layout example there is no difference between the new and old chip but i need confirmation.

    Hi Nicolas,

    There is no difference between the actual pinouts of the new and old chip, and you should follow the diagram found on the old datasheet (as it agrees with the layout examples for both versions as well as the diagram in the mechanical packaging information in the end of the datasheet). The pinout table itself remains correct in both versions, however. 

    Best,
