Working Principle

The MP20046DQ-G-LF-Z is a linear voltage regulator with a built-in power MOSFET, which acts as a switch to control the flow of current. The regulator’s input voltage is equal to the output voltage, and any variation in the input voltage is monitored and compensated by the regulator’s feedback circuitry with the help of a precision voltage reference. The output voltage is maintained at the set level, even under varying load conditions. The voltage regulator has a low on-resistance, which allows for efficient operation and lower consumption power. It also features over-voltage and over-current protection and a programmable soft-start function to reduce inrush current.
