The
VDD(STDBY)| and dVDD(STDBY)/dt system requirement can be used to define the component used for the VDD supply
generation. The following two examples describe how to calculate capacitance size:

1 VDD = 3.3 V ± 10% / 5.0 V ± 10%, TA = 40 to 125 °C, unless otherwise specified
2 This capacitance value is driven by the constraints of the external voltage regulator supplying the VDD_BV voltage.
A typical value is in the range of 470 nF.
3 This value is acceptable to guarantee operation from 4.5 V to 5.5 V
4 External regulator and capacitance circuitry must be capable of providing IDD_BV while maintaining supply VDD_BV
in operating range.
5 In-rush average current is seen only for short time (maximum 20 s) during power-up and on standby exit. It is
dependant on the sum of the CREGn capacitances.
6 The duration of the in-rush current depends on the capacitance placed on LV pins. BV decoupling capacitors must
be sized accordingly. Refer to IMREG value for minimum amount of current to be provided in cc.
