Figure 9. 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 Section 3.13: Recommended operating conditions).

The internal voltage regulator requires a controlled slew rate of both VDD_HV and VDD_BV as

described in Figure 10.
