The LM4040AIM3-2.5 device works by using a NPN BJT to act as a voltage reference. The voltage reference is connected to the base of the NPN BJT, which is in turn connected to a resistor. When a voltage is applied to the base of the NPN BJT, current will flow through the resistor and out to the output. As the input voltage is increased, the amount of current that is passed through the resistor will increase, thus increasing the output voltage.

To ensure accuracy and stability, the device requires a sense resistor. The sense resistor is placed in series between the input and the output of the device. The purpose of the sense resistor is to measure the voltage drop across it, which is then used to determine the output voltage of the device.
