Voltage Regulators - A Closer Look As we’ve seen in the section above, the primary job of a voltage regulator is to drop a larger voltage to a smaller one and keep it stable, since that regulated voltage is being used to power (sensitive) electronics. It also acts as a buffer to protect any component from damage. By contrast, a switching regulator uses an active device that switches on and off to maintain an average value of output. Because the regulated voltage of a linear regulator must always be lower than input voltage, efficiency is limited and the input voltage must be high enough to always allow the active device to drop some voltage. They provide very high degrees of regulation and low levels of ripple, although their levels of efficiency are much lower than another popular form of regulator called the switch mode regulator.
