Power supply scheme
1.
Each power supply pair must be decoupled with filtering ceramic capacitors as shown above. These capacitors must be
placed as close as possible to, or below, the appropriate pins on the underside of the PCB to ensure the good functionality
of the device.
2.
To connect REGOFF and IRROFF pins, refer to Section 2.2.16: Voltage regulator.
3.
The two 2.2 µF ceramic capacitors should be replaced by two 100 nF decoupling capacitors when the voltage regulator is
OFF.
4.
The 4.7 µF ceramic capacitor must be connected to one of the VDD pin.
