6-7-3 5V Application Circuit
When RA8806 operates in 5V system, 5V power inputs from VDDH and 3V power will output at
VDD that is the power to supply internal core. Users need to add 1µF and 0.1µF capacitors in
parallel at VDD to increase power stability.
Please note that DC-to-DC converter will increase some power consumption. So, if the RA8806
enter Sleep mode then it will keep around 20µA static current.
