In the LMR51610EVM, what are the purpose of R3 and C7? C7 looks like a feed-forward component, but why would it be positioned after R3, and what is R3 for?
Neither of these are in the datasheet, when should they be included?
Thanks.

hi, Oscar,
Both is optional for typical circuit application ,you can choose to solder on board or not.
R3 is for loop test injection signal reserved. and Cff is also a place reserve for loop stability test.

Thanks Elena,
So C7 is for testing stability? Or is it used to improve stability?
Just reserve for adjust, in case inductor, Vout cap, Vout voltage or anything change.
you can remove it.
