Voltage regulator
Regulator, designed to automatically maintain a constant voltage level;may: use a simple feed-forward design or include negative feedback, use an electromechanical mechanism or electronic components
A voltage regulator is a system designed to automatically maintain a constant voltage. It may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages. Electronic voltage regulators are found in devices such as computer power supplies wher... Wikipedia
