Ihc 7805 / LM7805CV / L7805CV Voltage Regulator IC 5V 1A (Pack of 5) by Indian Hobby Center… Motor Control Electronic Hobby Kit

7805 is a voltage regulator integrated circuit. It is a member of 78xx series of fixed linear voltage regulator IC. The voltage source in a circuit may have fluctuations and would not give the fixed voltage output. The voltage regulator IC maintains the output voltage at a constant value. The xx in 78xx indicates the fixed output voltage it is designed to provide. 7805 provides +5v regulated power supply. Capacitors of suitable values can be connected at input and output pins depending upon the respective voltage levels.
