In electronic products, linear voltage regulators. The resistance of the regulator varies depending on the input voltage and load, resulting in a stable voltage output. The conditioning device acts like a variable resistor, continuously conditioning the voltage divider network using active devices that can be turned on and off to adhere to the average output. Because it is necessary that the regulator voltage of the linear regulator is always lower than the input voltage, the power is limited, and the input voltage is necessary to be high enough to always drop some voltage from the active device.
