The working principle of the S-13R1E37-A4T2U3 is based on the linear voltage regulator. A linear voltage regulator works by using a transistor in a closed loop configuration to ensure constant current to the output terminal. The transistor has two input terminals, one called the driver, and the other called the error amplifier. The input to the error amplifier is the reference voltage, which is typically set at the desired output level for the regulator. The output of the error amplifier is then fed back to the driver, which is used to adjust the transistor’s output to maintain the reference voltage. Therefore, a linear voltage regulator is able to provide a constant and stable output voltage, even if the input voltage varies.

The S-13R1E37-A4T2U3 functions by using a series of transistor circuits in a voltage divider configuration. The circuit is designed to compare the input and output voltage, and the difference between them is amplified and the output control is adjusted accordingly. Case and package ground creates stability in the output voltage and the transistors are used to control the output and regulate it. This provides an extremely effective and low-cost solution for accurately controlling the output voltage of the regulator.
