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 Table 40. Care should be taken to limit the series inductance
to less than 15 nH.

Legend: ESR is the equivalent series resistance and ESL is the equivalent inductance.
10.3.2
Supply current characteristics
The current consumption is measured as described in Figure 10 on page 65 and Figure 11
If not explicitly stated, general conditions of temperature and voltage apply.
