Ic 7812 Pin Diagram. The pin 2 is common between both input as well as output voltage. A classic example can be seen in this article where a 7805 ic is used as a cell phone charger regulator.
It can deliver an output current not more than 1a. Identifying 7805 7812 7824 ics pinouts. The positive input is at pin 1.
The 7812 ic have 3 pins.
We use an lm7812 voltage regulator ic for 12v and lm7912 for 12v. Output transistor safe area protection is also one of the features of these ics. 7812 pin and circuit diagram 7812 is a famous ic which is being widely used in 12v voltage regulator circuits. Truly speaking it is a complete standalone voltage regulator.
