Working Principle

The S-1335B27-N4T1U3 is a linear voltage regulator that works by controlling the output voltage of the regulator with an internal voltage reference. The device is connected to an input voltage source and an output voltage load. When the input voltage exceeds the output voltage, a difference in potential will be present, allowing current to flow from the input to the output. The voltage reference used by the regulator determines how much current is allowed to flow from the input to the output. An internal resistor called a shunt resistor is used to measure the current flowing through the device. The voltage drop across the shunt resistor is compared to the voltage reference, and this comparison determines how much current is allowed to flow from the input to the output. If the current is too high, the voltage regulator will reduce the voltage difference between the input and the output until the reference voltage is reached. This process is continuous, ensuring that the output voltage remains constant and within tight linear tolerances.

Conclusion

The S-1335B27-N4T1U3 is a linear voltage regulator that is widely used in automotive and industrial applications. The device provides precise voltage regulation while allowing the user to regulate current within tight tolerances. It works by controlling the voltage difference between the input and output using an internal voltage reference and shunt resistor.
