A 12-0-12 regulator is a type of voltage regulator that is commonly used in electronic circuits to regulate the voltage of a DC power supply. It is designed to output a stable DC voltage of +12V, 0V, and -12V, and is typically used to power operational amplifiers (op-amps) and other analog circuits that require dual power supplies.
Note: If you don’t have a dual power supply transformer then don’t buy it. It will not work with a single power supply.

how to use a 12-0-12 regulator? –
Connect the input voltage: Connect the positive and negative terminals of your DC power supply to the input pins of the regulator. The input voltage should be higher than the output voltage of the regulator.
Connect the output voltage: Connect the +12V, 0V, and -12V output pins of the regulator to your circuit, using wires or connectors as needed.
Check the output voltage –
Use a multimeter to check the output voltage of the regulator. The +12V output should measure 12 volts, the 0V output should measure 0 volts, and the -12V output should measure -12 volts.
Terminals –
Two Outer Terminals (Identical Voltage) –
These terminals typically have the same voltage rating, designated as 12V in your case. They represent the two ends of the transformer’s secondary winding. The two outer terminals are for the AC input you want to step down.
Center Terminal (0V) –
This is the center tap, acting as a common ground connection. The center terminal and one of the outer terminals provide the AC output for the ground. You can choose either outer terminal depending on your circuit’s needs (positive or negative voltage).
Test your circuit –
Once the regulator is connected and the output voltage is verified, you can connect your circuit to the regulator and test it to make sure it is functioning correctly.
It’s important to note that while the 12-0-12 regulator provides dual power supplies, the overall power output of the regulator may be limited. Be sure to check the regulator’s specifications to ensure that it can supply enough power for your circuit
Note: We have used Basson 12-0-12 Regulator, I have given 24-0-24 dc input and got 12-0-12 one amp output, which was not sufficient for the power amplifier but it was okay for the pre-amp board.
FAQs –
12-0-12 Regulator works with single DC Supply?
No, a 12-0-12 regulator is not designed to work with a single DC supply. It requires a dual DC supply, which means that there are two separate DC voltage sources, one positive and one negative, that are connected to the regulator.
How to use a 12-0-12 Voltage regulator with a single supply?
you can use a single power supply and a voltage regulator that provides a fixed output voltage, such as a 7812 regulator for a +12V output and a 7912 regulator for a -12V output. However, this will not provide a true dual power supply, and may not be suitable for all applications.
12-0-12 Regulator work with AC or DC?
A 12-0-12 regulator can work with either AC or DC input voltage, but it typically requires a DC input voltage to provide a stable DC output voltage.
How can I reduce the noise of my amplifier?
A 12-0-12 regulator can help reduce noise in an audio amplifier by providing a stable and regulated power supply. Noise in an audio amplifier can be caused by many factors, including power supply ripple, ground loop interference, and electromagnetic interference (EMI).
