What is Voltage regulator?
[[File:Voltage Regulator.png|thumb|Two different sizes 5Volts regulators]] '''Voltage regulator''' is an [[Electronic component|elecrical component]] that maintains a constant [[voltage]] level. It stabilizes the voltage. For example, when a voltage regulator is fed a voltage that varies betveen 7.5 - 9.0 Volts, the regulator's output stays at exactly 5 Volts. Another way to stabilize voltage is by using a [[zener diode]]. {{Electronic components}} {{Commonscat|Voltage regulators}} [[Category:Electronic components]] {{tech-stub}}
