TPS7A91: Layout Review

Desireddy Teja Reddy

Part Number: TPS7A91

Hi Team,

We are using the TPS7A9101DSK LDO part in our Layout Board file. I had attached the images of the Board file and Schematics. Please review the layout and share your feedback with us.

The PCB we are using is of 12 Layers:

IC - Place on top

Layers 2,4,9 and 11 are Ground

Note: R635 is No Mount

Thanks and regards

- Teja.

Hi Teja,

This layout looks good. I am curious about C99 in your schematic, the NR/SS capacitor. Where is that located in your layout?

BR,

Erin
