Voltage Regulator

A voltage regulator is a crucial electronic component used to stabilize and maintain a constant output voltage in electronic circuits. It acts as a control mechanism to ensure that the voltage supplied to devices remains within a specific range, regardless of fluctuations in the input voltage or load variations.

In situations where the input voltage is higher than the required output, a buck converter (step-down) setup is employed, which efficiently lowers the voltage while stepping up the current. Conversely, when the input voltage is lower than the desired output, a boost converter (step-up) setup is used to increase the voltage while reducing the current, ensuring a steady and reliable power supply to connected devices.
