TLV707: Asking for the TLV series LDO layout design review

Part Number: TLV707

Hi Sir,

 

My customer would like design TLV series LDO.

Would you please review schematic and layout and provide your comment?

Design material

 

 

BR,

SHH

  • Hi SHH, 

    I was able to look through the design. 

    It seems that:

    U200 = U701 [Page 4]

    U306 = U702 [Page 5]

    U305 = U703 [Page 5]

    U403 = U710 [Page 6]

    I cant seem to find U303 from the table

    Best,

    Juliette

  • Hi Juliette,
