Put all compontents on 5V rail and use a (variable) load resistor on 3.3V to simulate use
also kind of related to #8 (closed)

For implementation examples, look at the already finished entities. The current implementation is a voltage follower that allows for roughly 0.8A of load on the global 3.3V Rail. It can be controlled by outputting an analog voltage with the ESP32's DACs. Only one channel is needed. There are 2 circuits currently in the schematic, one of them is an "alternative" in case parts aren't available. Instead of using a high power OpAmp, it uses a regular OpAmp and an n-channel mosfet to drive the load. The Output Voltage of 0-3.3V should result in a current of 0-0.8A, however this hasn't been verified on real hardware yet. It is possible that due to limits in the DAC's Output (not quite reaching 0V or 3.3V) or a voltage drop inside the OpAmp the min/max load is shifted or that the maximum current is already achieved with a DAC output voltage lower than 3.3V. So Characterization of DAC-Voltage/Current is needed.
