Hello,

I m designing a board with a STM32F103. I was wondering about capacitors value. In STM32 documentation, it's written to use 100nf per VDD PIN + one 4.7uF.

On the other side, I m using a low dropout regulator :

I dont' understand where to place the 4.7uF capacitor...

If you could help me, I will be thankful :)

Regards,

Aurélien
