Hi Siddhi,

If so, I will go ahead and close that other thread.

After reviewing the layout, I highly recommend adding a second Cout as there is still space to add some extra cap. There is no need to install the second one, but it doesn't hurt having the extra space.

Is there a reason to have the 0ohm jumper at the output? Nothing wrong with having it there, it seems it would be better to have one solid Vout plane on the bottom and share this with the 1.8V plane in layer PWR.

Best,

Edgar Acosta
