Working Principle

The S-1131B23UA-N4ITFU utilizes an advanced linear voltage regulator IC which works by stepping down the input voltage to a desired output voltage. Internally it has an amplifier, a voltage reference and a feedback loop with an error amplifier. When the output voltage is applied to the output terminals, feedback signals are created which are applied to the error amplifier. The error amplifier compares this signal with the reference voltage and sends a control signal to the amplifier. The signal then adjusts the amplifier so that the output voltage remains consistent. It also features additional protection circuitry and current limit circuitry to prevent overvoltage and overcurrent conditions. Overvoltage protection circuitry limits the maximum output voltage to a safe level. The current limit circuitry limits the maximum current output from the device.
