Voltage regulator IC's are the IC’s that are used to regulate voltage. IC 7805 is a 5v Voltage regulator that restricts the voltage output to 5v. It comes with provision to add heat sink. The maximum value for input to the voltage regulator is 35v. It can provide a constant steady voltage flow of 5v for higher voltage input till the threshold limit of 35v. If the voltage is near to 7.5v then it does not produce any heat and hence no need for heat sink. If the voltage input is more, then the heat produced is more.
Led or Light emitting diode is a small diode which emits light when connect in forward bias to a power source. Leds are used as an indicator in many device and are increasingly use as a light source at homes and office.
A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits.
