What is the STM32WL55 LDO mode output capacitor value on the VFBSMPS pin?

The datasheet indicates the value of 470nF for the SMPS mode on the VFBSMPS pin. But for the LDO mode, I didn't find the required value.

Thanks

Hello @AO.2​  and welcome to the community,

For LDO mode, you just have to remove the SMPS coil and keep the 470nF capacitance as you can see in the figure 3 of the datasheet .

Best regards
