Description

7912 12V Linear Negative 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 7912 IC is a negative 12V regulator, meaning it provides 12V as output. The name 7912 signifies two meanings, “79” indicates negative and the term “12” indicates the voltage. So “7912” means that this IC will regulate a negative 12V output voltage.

When you are designing an analog circuit, the circuit might need negative voltage either as a power source or as a reference voltage. In both cases, 7912 will be an ideal choice when you need a negative 12V. The output current of this IC is up to 1A, however, with an appropriate heat sink, the datasheet says that a peak current of 2.2A can be achieved through this IC.Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed.

LM7912 

The LM7912  is a three-pin IC.
Pin 1 (Ground ): Connected to Ground.
Pin 2 (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 3 (Output): The Output pin is the regulated -12 volts DC.
