Electrical characteristics

STM8S105xx

10.3.1

VCAP external capacitor

Stabilization for the main regulator is achieved connecting an external capacitor CEXT to the

VCAP pin. CEXT is specified in the Operating conditions section. Care should be taken to limit

the series inductance to less than 15 nH.
