Hi Mr./Mis,

Is there any risk in using the LP3891 instead of the Richtek DS9183?

Alex,

No issues using LP3891, but it's a legacy device. We do recommend looking at TLV761 or TLV767 for newer options.

Thanks,

Prakash L

Hi Prakash,

Thank you for your suggestion. However, I prioritize a pin-to-pin compatible solution for the current project. My colleague also suggested the LP38502-ADJ, which seems more suitable for our requirements. I would appreciate any feedback regarding potential risks with this solution.

Alex,

No issues using LP38502-ADJ if you need p2p.
