Operating Principle

S-1142C37H-E6T2U utilizes a linear voltage regulation technique that operates by comparing the output voltage of the device to a reference voltage, and then adjusting its internal components to modify the output level to match the set level.The device consists of an error amplifier and a series of pass transistors. The pass transistors are connected in series with an output capacitor and an inductor. When the voltage at the output is greater than the reference voltage, the error amplifier induces a current flow in the pass transistors. The current flow in the pass transistors increases the voltage drop across the series, reducing the output voltage until it matches the target level. If the voltage at the output is lower than the reference voltage, the current flow in the pass transistors will be decreased, thus increasing the voltage drop across the series. This will result in an increase in the output voltage until it matches the target level.

Conclusion

S-1142C37H-E6T2U is a linear voltage regulator that offers diversified voltage stabilization mechanisms with minimal power loss and tightly regulated output. It has a wide voltage output range from 1.5V to 37V and a high current capability of up to 3A. Additionally, it provides protection against over current and overvoltage, making it well suited for applications where safety and reliability are important.
