Working Principle of S-817B48AY-B2-U

A linear voltage regulator is an electrical regulator that regulates the output voltage by controlling the current in the main circuit. The main principle of linear voltage regulator is that the voltage at its output must be equal to its reference voltage, which is typically connected to the device’s ground. The output voltage is determined by the values of two resistors in the feedback loop: R1 and R2.

This type of voltage regulator achieves its regulation by changing the average current flowing in the main circuit. It does this by controlling the amount of current in the drive circuit, which is connected in series to the main circuit. The linear voltage regulator utilizes the transistor-based power device to control the current. It can be used for both positive and negative DC operation.
