voltage regulator[′vōl·tij ‚reg·yə‚lād·ər]
A device that maintains the terminal voltage of a generator or other voltage source within required limits despite variations in input voltage or load. Also known as automatic voltage regulator; voltage stabilizer.
An automatic electric control device whose output provides a constant voltage supply, even though the line voltage at its input may vary.
voltage regulatorAn electronic circuit used to maintain a level amount of voltage in an electrical line. It eliminates power surges, spikes and brownouts, which can cause harm to sensitive electronics. A voltage regulator "module" (VRM) is a voltage regulator in a replaceable unit.
Voltage Regulators and Stabilizers
Regulators and stabilizers do the same thing. However, voltage regulators generally deal with output from DC power sources, whereas voltage stabilizers and conditioners typically maintain AC line voltage. See surge suppression and UPS.
