How Does it Work?

The internal architecture of the S-1132B22-M5T1G is based on a linear regulator. It contains an internal power MOSFET, an error amplifier, and feedback circuitry. It works by comparing the output voltage to a reference voltage and controlling the gate voltage applied to the power MOSFET switching its current on or off in order to regulate the output voltage. The output voltage is proportional to the difference between the input voltage and a reference voltage set internally. The output voltage can be finely adjusted by adjusting an external resistor divider network.
