Working Principle

The S-13R1C20-N4T1U3 is a linear voltage regulator, meaning it can control and maintain a steady output voltage without the need for high-frequency switching. Unlike switching converters and other regulators, the S-13R1C20-N4T1U3 utilizes a linear regulator circuit to accurately regulate its output voltage.The S-13R1C20-N4T1U3 regulator consists of three primary components: a pass transistor, a sense resistor, and a feedback loop control circuit. The sense resistor monitors the output voltage and the feedback loop compares the voltage on the output terminal to a reference voltage. If the output voltage is greater than the reference voltage, the control circuit reduces the base current of the pass transistor, which subsequently reduces the output current, bringing the output voltage back to the desired level. Conversely, if the output voltage is less than the reference voltage, the control circuit increases the base current of the pass transistor, resulting in higher output current and output voltage. This process is repeated constantly to ensure that the output voltage remains consistent and within the desired limits.Additional integrated features of the S-13R1C20-N4T1U3 such as thermal shutdown, current limit protection, and soft-start circuitry ensure the device is safe under all conditions and contribute to its superior performance characteristics.
