Peripheral element lm78 / lm79 series to form three-terminal regulator IC power regulators rarely needed, as well as the internal circuit overcurrent protection circuit overheating and adjust the tube, use, reliable, convenient, and cheap. The family of integrated voltage regulator IC models or lm79 lm78 behind the figures represent the three-terminal integrated voltage regulator circuit output voltage, such as lm7806 represents the output voltage is positive 6V, lm7909 represents the output voltage is negative 9V. Because the three-terminal integrated and easy to use fixed voltage regulator circuit, often used in electronic production.
