The voltage range of VCC (3.0 V ~ 3.6 V) has already included the ripple voltage.

Since the product has capacitors inside, inrush current occurs during power-on. You should evaluate in the actual
environment in order to check the effect of the supply voltage drop caused by inrush current in the system.
