92 / 227 page  Electrical characteristics STM32H723xE/G 92/227 DS13313 Rev 2 6.3.2 VCAP external capacitor Stabilization for the main regulator is achieved by connecting an external capacitor CEXT to the VCAP pin. CEXT is specified in Table 14. Two external capacitors can be connected to VCAP pins. Figure 12. External capacitor CEXT 1. Legend: ESR is the equivalent series resistance. Table 13.

VCAP 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. Symbol Parameter Conditions CEXT Capacitance of external capacitor 2.2 µF(2)(3) 2. This value corresponds to CEXT typical value. A variation of +/-20% is tolerated. 3. If a third VCAP pin is available on the package, it must be connected to the other VCAP pins but no additional capacitor is required. ESR ESR of external capacitor < 100 m Ω MS19044V2 ESR R Leak C |
