VREG
Application Information
7.
7.1.
It is mandatory to add 1 µF (low ESR) between VREG and GND.
Decoupling capacitors are not all drawn. It is recommended to add 100 nF decoupling
capacitor for every VDD and VDD_IO pin. In order to reduce noise on the antenna inputs it is
recommended to add 27 pF on the VDD pins close to the antenna interface.
