Where to Use the L7812CV Voltage Regulator?
The L7812CV voltage regulator IC is ease-of-use and available at a very low cost. This allows for a higher operating frequency and lowers supply current, therefore helping to reduce power consumption. It is general use and is suitable for a range of applications, such as power management.
How To Use L7812CV?
When you use the regulator setting, the current flowing through the device should not exceed the capacity mentioned in the L7812CV datasheet, otherwise, it could easily be damaged. Be careful when connecting to a voltage source. The opposite polarity heats up the device quickly. You can also use a PN junction diode and avoid this situation.
Everything You Need to Know About Voltage Regulator IC in Electronics
What is L7812CV?
The L7812CV is a sort of positive voltage regulator with a three-terminal. It can offer local on-card regulation, helping eliminate the distribution problems associated with a single point of regulation.
How does an L7812CV voltage regulator work?
The L7812CV is a type of positive voltage regulator. In a circuit where both the positive and negative voltage supplies are required, the simplest solution is to use two separate circuits with two separate DC sources to make sure that you do not get both positive and negative voltages at the same time. Be careful when connecting to a voltage source. The opposite polarity heats up the device quickly. You can also use a PN junction diode and avoid this situation.
How do you test a linear voltage regulator?
We can test it with a multimeter probe. In general, red probes are positive and black probes are negative. We need to place the positive probe on the input pin of the voltage regulator and the negative probe on the ground pin. At this point, the voltage we read should be higher than the voltage regulator-rated output.
What is the difference between 7812 and 7912?
7812 refers to the positive bus voltage regulator. 7912 refers to the negative bus voltage regulator.

Conclusion
In short, the L7812CV voltage regulator is a positive voltage that respects the common ground because it has resistors and some kind of a fixed input. In a circuit where both the positive and negative voltage supplies are required, the simplest solution is to use two separate circuits with two separate DC sources to make sure that you do not get both positive and negative voltages at the same time.
