LM317: DCY Package (4-Pin SOT-223)

Part Number: LM317

Tool/software:

Hi,

Does the figure 5.1 (DCY Package) is correct in the last revision of the datasheet (revZ)?

I think there is a issue with the pinout. Pin 1 (ADJ) should be to the left.

Best,

Yohann

    Hello Yohann, 

    Thank you for your question, you are correct this is a typo in the datasheet for DCY package. Adjustable is pin 1 but should be labeled 1-3 from bottom to top. Bottom table below is the correct pinout, in addition in the application section it shows the correct layout and associated pin out.

    Thank you for bringing this to our attention, hopefully this helps!
