7805 Ic Circuit Diagram. Down below is a typical application circuit of the lm7805 ic which lm7805 work as 5v voltage regulator. The output current of this ic can go up to 1 5a.
A voltage regulator ic maintains the output voltage at a constant value. So our 7805 will provide a 5v output voltage. Here it is connected to a 3 9 volt zener diode.
Normally the pin2 of the regulator ic is connected to the ground.
7805 voltage regulator a member of 78xx series of fixed linear voltage regulators used to maintain such fluctuations is a popular voltage regulator integrated circuit ic. This is attained by adding two resistors r1 and r2 as shown in figure. Normally the pin2 of the regulator ic is connected to the ground. This circuit can built with a step down transformer 230v 12v bridge rectifier fuse 1a capacitor 1000μf ic 7805 voltage regulator capacitors 0 22μf 0 1μf diode 1n4007.
