Power supply

The power supply subsystem supplies power to the MCU, communication interface , and various circuits on the PCB. This subsystem is typically realized using a Low Dropout (LDO) regulator and could include diagnostic features such as watchdog and supply voltage monitoring. In addition, the power supply subsystem could include tracking regulators that provide power to off-board sensors.
