A Voltage Regulator

A voltage regulator is an integrated circuit that outputs a specified direct current voltage. It is necessary in applications where a certain constant and consistent level of direct current voltage is needed in a circuit. A circuit may need a consistent direct current voltage of 3 volts. There are 3 voltage regulators. A circuit may need a consistent direct current voltage of 18 volts. Then the circuit designer would use a 18-volt regulator to provide 18 volts consistently to a circuit. You may probably get the point that a voltage regulator is used in applications in circuits where a specific, constant direct current voltage output is needed.

Voltage regulators are widely used in variety of electronic circuits. This is because electronic components, especially microelectronic circuits, which contain components such as ICs, cannot work if they were supplied with high voltage. They are voltage-sensitive devices that are easily destroyed and become useless in a high voltage condition. These devices function only on low voltage, so they are used in conjunction with voltage regulators, which outputs low direct current voltage.
