6.3.2
VCAP_1/VCAP_2 external capacitors
Stabilization for the main regulator is achieved by connecting the external capacitor CEXT to
the VCAP_1 and VCAP_2 pins. For packages supporting only 1 VCAP pin, the 2 CEXT
capacitors are replaced by a single capacitor.
CEXT is specified in Table 18.
Figure 23. External capacitor CEXT
1. Legend: ESR is the equivalent series resistance.

Operating conditions at power-up/power-down (regulator ON)
Subject to general operating conditions for TA.
Table 19. Operating conditions at power-up / power-down (regulator ON)
Table 18. VCAP_1/VCAP_2 operating conditions(1)
1. When bypassing the voltage regulator, the two 2.2 µF VCAP capacitors are not required and should be
replaced by two 100 nF decoupling capacitors.
