About Voltage Regulators
Voltage regulators are power converters that provide voltage control capabilities. They accept a voltage that varies over a given range and generate an output voltage that does not vary. Unlike integrated circuit (IC) voltage regulators and IC switching regulators, non-IC voltage regulators do not use an active pass element or other semiconductor. There are two basic types of non-IC voltage regulators: switching types and all others, mainly linear and shunt types. Unlike a switching voltage regulator, a linear voltage regulator or shunt voltage regulator is limited by the fact that its output voltage must remain less than its input voltage. Also, the efficiency of most switching regulators is better than that of an equivalent linear or shunt regulator.
