In general, linear voltage controllers are far more efficient and easy to operate than equivalent voltage controlling circuits made up of sensitive components, such as Zener or transistor and op-amp.
These positive voltage controls generate an accurate and consistent output voltage ranging from around 5 volts to approximately 24 volts for several electronic connections.
These three-terminal fixed tension controls are available in various ways, each with their incorporated voltage controls and circuits that limit current. This allows us to design a wide variety of power and output rails, single or dual, for most electronic circuits and applications. There are also variable voltage linear controllers that offer a continuously varying output voltage from just above null to several volts below their maximum output.
