VCAP external capacitor

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

VCAP pin. CEXT is specified in Table 24. Care should be taken to limit the series inductance

to less than 15 nH.

Supply current characteristics

The current consumption is measured as described in Figure 9 on page 59 and Figure 10

on page 60.

If not explicitly stated, general conditions of temperature and voltage apply.
