What Is Voltage Regulator

A voltage regulator will limit the maximum amount of voltage from a power source and prevents a device or alternator from shorting and overheating.

What is voltage regulator. The linear voltage regulator is the easiest type of voltage regulator. A voltage regulator may use a simple feed forward design or may include negative feedback. The voltage regulator is provided in more than one point in the power system for controlling the voltage variations. If you have electrical equipment that won t turn on that could.

As we ve seen in the section above the primary job of a voltage regulator is to drop a larger voltage to a smaller one and keep it stable since that regulated voltage is being used to power sensitive electronics. The resistance of the regulator varies in accordance with both the input voltage and the load resulting in a constant voltage output. In electronics a linear regulator is a system used to maintain a steady voltage. A voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions.

Linear and switching a linear regulator employs an active bjt or mosfet pass device series or shunt controlled by a high gain differential ampl. Their secondary use is also to protect the circuit against voltage spikes that can potentially damage fry them. Depending on the design it may be used to regulate one or more ac or dc voltages. It is available in two types which are compact and used in low power low voltage systems.

In dc supply system the voltage can be controlled by using over compound generators in case of feeders of equal length but in the case of feeders of different lengths the voltage at the end of each feeder is kept constant using feeder booster. Voltage regulator any electrical or electronic device that maintains the voltage of a power source within acceptable limits. The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage. It may use an electromechanical mechanism or electronic components.

Let us discuss different types of voltage regulators. Voltage regulators are commonly found in vehicles and other electronic equipment. Signs of a bad voltage regulator in a vehicle include dimming or pulsing lights or a dead battery. With the linear regulator you ll be taking advantage of a power transistor bjt or mosfet that plays the role of a variable resistor raising and lowering the output voltage of your circuit as your input supply changes.

Voltage regulators a closer look. This type of regulator acts as a voltage divider on your circuit and is the kind of regulator commonly used when you re designing low power and low cost applications. There are two types of voltage regulators. The regulating device is made to act like a variable resistor continuously adjusting a voltage divider network to maintain a constant output voltage and continually dissipating.

Voltage regulators used in low voltage electronic devices are usually integrated circuits.
