  • RE: ATL432B: ATL432BQDBZR, temp affects output voltage

    Hi, It seems your design is causing issues with one ATL432 but not another. I believe this could be a compensation issue. Can you try increasing the values of C30 and see if that changes anything? -Marcoo

  • RE: TL432B-Q1: Build LDO with TL432, high output ripple

    Resolved
    Hi Sheldon, This oscillation is occurring because seemingly the phase margin is low. You should be able to correct this by adding a capacitor between the cathode and reference. Second, probe your cathode pin and I think you won't have enough input…
