Description

7812 12V Linear Positive Voltage Regulator IC

Voltage regulators are very common in electronic circuits. They provide a constant output voltage for a varied input voltage. In this case, the 7812 IC is a Positive 12V regulator, meaning it provides 12V as output. The name 7812 signifies two meanings, “78” indicates positive and the term “12” indicates the voltage. So “7812” means that this IC will regulate a positive 12V output voltage. (Click for more voltage regulators ).

When you are designing an analog circuit, the circuit might need a positive voltage either as a power source or as a reference voltage. In both cases, 7812 will be an ideal choice when you need a positive 12V. The output current of this IC is up to 1.5A, however, with appropriate heat sink, the datasheet says that a peak current of 2.2A can be achieved through this IC.

 

7812

The LM7812  is a three-pin IC.
Pin 1 (Input): The Input pin is the pin that accepts the incoming DC voltage, which the voltage regulator will eventually regulate down to +12 volts.
Pin 2 (Input): Connected to Ground.
Pin 3 (Output): The Output pin is the regulated +12 volts DC.
