    Hello SHH, 

    For a 12V application we recommend the TL431 or ULH431 instead. For the 2.49V reference. 

    If you are wanting to review the schematic, please use the PoE Schematic review guide. 

    If this post answers your question, please indicate so by marking this thread as resolved. Thank you.

    Hi Michael,

    thanks for feedback.

    could I know what is the parameter that TLV431 cannot support?

    TLV431: Output voltage can be set to any value between VREF (1.24 V) and 6 V

    TL431: The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V

    BR,
