It features both a low-dropout voltage regulation function and an over-current protection feature which work to ensure low power loss and high power efficiency.FAN2518S28X Working Principle The FAN2518S28X voltage regulator IC works by converting an input voltage that is higher than the desired output voltage and then regulating it to the desired output voltage. This is achieved by using transistors, resistors, capacitors and other components, which form the linear voltage regulator. When the input voltage is lower than the required output voltage, the regulator gains extra current through a loop called an error amplifier.This loop corrects the voltage level of the output and helps to keep the output voltage stable. The error amplifier compares the output voltage to a reference voltage and the difference between these voltages is the error voltage which is then sent to the regulator.The voltage regulator then adjusts the transistor’s bias to keep the output voltage at the desired level. The FAN2518S28X also features a stand-by control input and an overvoltage protection circuit which help to protect the device against overvoltage and short-circuit conditions.ConclusionThe FAN2518S28X is a linear voltage regulator IC specifically designed by FANUC Electric Co., Ltd. as a cost-effective, efficient and reliable solution for various applications.
