Working Principle

FAN2515S26X is a low-voltage, low-dropout linear regulator, which works by using a pass-gate transistor based on a voltage divider formed by two resistors. The resistors set the output voltage, usually a negative voltage, relative to the input voltage, usually a positive voltage. A feedback loop formed by a sense resistor compares the output voltage with a reference voltage, which is controlled by adjusting the gate voltage of the pass gate transistor. When the output voltage is lower than the reference voltage, the gate voltage increases so the pass gate transistor turns on, allowing more current to flow through the output voltage and thus increasing the output voltage. Conversely, if the output voltage is higher than the reference voltage, the gate voltage decreases, and the pass gate transistor turns off, reducing the current, and thus lowering the output voltage.

FAN2515S26X provides low noise, low quiescent current, and low dropout voltage. It is designed to deliver high output accuracy and stability and ultra-low noise along with temperature compensation.
