L7805CV - Three-terminal regulator IC

Introduction:

In electronic products, the common three-terminal regulator IC has a positive voltage output of 78 & TImes; & TImes; series and negative voltage output of the 79 & TImes; & TImes; series. As the name implies, the three-terminal IC refers to the integrated circuit for this voltage regulation. There are only three pins for output, which are the input terminal, the ground terminal and the output terminal. It looks like a regular triode, the TO-220 standard package, and the 9013 look of the TO-92 package.

The 78/79 series three-terminal regulator IC is used to form a regulated power supply with few external components. The circuit also has overcurrent, overheat and regulation tube protection circuits, which are reliable, convenient and inexpensive. The numbers behind the 78 or 79 in this series of integrated regulator IC models represent the output voltage of the three-terminal integrated regulator circuit. For example, 7806 indicates that the output voltage is positive 6V, and 7909 indicates that the output voltage is negative 9V.

Because the three-terminal fixed integrated voltage regulator circuit is convenient to use, it is often used in electronic production.
