Everytime we start adding new peripherals, sensors and actuators to our projects, we eventually will reach a point where the 3.3 and 5 V voltages from the microcontroller (when they are available) are not enough, either because we require more current than what the MCU pins can deliver, or we have different voltage requirements.
