Ic 7805 Symbol. The name 7805 signifies two meaning 78 means that it is a positive voltage regulator and 05 means that it provides 5v as output. In our case the 7805 ic is an iconic regulator ic that finds its application in most of the projects.
Currently the 7805 voltage regulator ic is manufactured by texas instruments on semiconductor stmicroelectronics diodes incorporated infineon technologies etc. For 7805 ic it is 5v dc regulated power supply. Although many types of ic regulators are available the 7800 series of ic regulators is the most popular.
So our 7805 will provide a 5v output voltage.
Current rating i c 1a. Although many types of ic regulators are available the 7800 series of ic regulators is the most popular. For ics within the 78xx family the xx is replaced with two digits indicating the output voltage for example the 7805 has a 5 volt output while the 7812 produces 12 volts. They are designed to provide a constant 5v.
