Hello!

Our schematic uses SYS output only. PMID and LS/LDO aren't used.

Can we remove the capacitors for PMID, LS/LDO, and VINLS pins from the schematic?

Kind regards,

Hi L,

Capacitors for PMID are still necessary as that node is the input for the SYS node. Not including the LS/LDO and VINLS capacitors should be ok if the LDO rail is not planned to be used.
