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
