Voltage regulator

A voltage regulator is an electrical component. The voltage regulator keeps the voltage at a constant value. This is independent of the load and fluctuations in the supply voltage. There are different types of voltage regulators. Two popular voltage regulators are the LM317T and LM3940. The LM317T is adjustable over a range of 1.2 to 37V. The LM3940 is designed to convert 5V to 3.3V
