LM7809T Voltage Regulator

Voltage regulators are generally used in circuits that are used to charge batteries, power chips that are sensitive to changes in voltage. Most modules, such as Arduinos, charging modules and step-up or step-down modules make use of voltage regulators to regulate the output voltage to ensure that a constant output voltage is given to protect the rest of your circuit.
