Power supply configuration diagram for IoT devices

Power supply configuration example for IoT devices composed of power management IC with ultra-low supply current, low noise, and low electromotive force.

w80p rsp_w100p
The total of all supply current of our products including R1800, RP604, RP511/RP512, and RP118 comes to 944 nA.
It is equivalent to about 240 years* of battery life calculated from the AA battery capacity.

* Theoretical calculation value
