Working Principle of AP7343D-20FS4-7B

AP7343D-20FS4-7B voltage regulator uses a linear regulation method to provide a stable output voltage. The circuit works according to the basic voltage regulation principle, which is when the input voltage is higher than the output, the linear regulator operates in the active region, pulling down the output until the voltage is equal to the reference. If the input voltage is lower than the output voltage, the voltage regulator operates in the current limit region, pulling down the output as the current flow decreases. In both cases, the changes in the output voltage are proportional to the changes in the input voltage.
