78XX Voltage Regulators

The 78XX family of voltage regulators is extremely popular. These devices are known as three terminal regulators, as they come in packages with just three pins. Pin 1 is for the input voltage, pin 2 is for the output voltage, and pin 3 is for ground. There are three devices: the 7805 for a +5 volts output, the 7812 for a +12 volts output, and the 7815 for a +15 volts output. The minimum input voltage should be two volts more than the rated output voltage, and can vary up to +35 volts. The 78XX series can provide a stable, constant output voltage over that range of input voltages with up to one ampere of output current. If the circuit should suddenly demand more than one amp of current (as might be the case with a short circuit), the 78XX regulators include on-chip protection circuitry that will shut down the regulator before it can be destroyed by overheating.
