Voltage regulator capacitance connection The internal voltage regulator requires external capacitance (CREGn) to be connected to the device in order to provide a stable low voltage digital supply to the device. Capacitances should be placed on the board as near as possible to the associated pins. Care should also be taken to limit the serial inductance of the board to less than 5 nH. Each decoupling capacitor must be placed between each of the three VDD_LV/VSS_LV supply pairs to ensure stable voltage (see 4.4, Recommended operating conditions). Table 25.
