Working Principle

The SPX3940M3-L-3-3 is a monolithic linear regulator that follows the basic principle of linear voltage regulation. It is composed of a series of resistor-capacitor (R-C) circuits and a voltage reference. When the input voltage and the reference voltage are the same, no current passes through the regulator. However, when the input voltage is higher than the reference voltage, the output current increases. This allows the regulator to adjust the voltage to the desired level by controlling the output current. The SPX3940M3-L-3-3 features over-voltage, over-current and thermal protection for added safety and reliability.
