1. Each power supply pair must be decoupled with filtering ceramic capacitors as shown above. These
2. To connect REGOFF and IRROFF pins, refer to
3. The two 2.2 µF ceramic capacitors should not be connected when the voltage regulator is OFF.
4. The 4.7 µF ceramic capacitor must be connected to one of the VDDx pin.
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.
