CIN(1)Input regulator decoupling capacitors on VDDIO, VDDIOB and VDDANA --10-µF
Ceramic dielectric X7R-100-nF
COUT(2)Output regulator decoupling capacitors on VDDCORE-3.764.7-µF
Ceramic dielectric X7R-100-nF
ESR COUTExternal Series Resistance of COUT---0.5
Note:
  1. It is recommended to use ceramic X7R capacitor with low-series resistance. Refer to Power Supply Connections for a typical circuit connections.
  2. It is recommended to use ceramic or solid tantalum capacitor with low ESR.
