10.3.1 VCAP external capacitor
Stabilization for the main regulator is achieved connecting an external capacitor C
EXT
to the
V
CAP
pin. C
EXT
is specified in Table 26. Care should be taken to limit the series inductance
to less than 15 nH.

1. 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 8 on page 56 and Figure 9 on
page 57.
If not explicitly stated, general conditions of temperature and voltage apply.
