Low Noise Regulator

Intro

Voltage regulators are an important part of a power supply system. The function of a standard 3-pin regulator is to stabilise supply voltage, but all regulators generate noise from their own operation. The noise will then feed into the rest of the circuitry. Of course, to Team Burson and those who love pure music, a standard power regulator is just not good enough!

What is a Burson Low Noise Regulator?

Burson Low Noise Regulator (LNR) are a direct replacement for some of the most commonly used regulators in the market, based on the same technology from Burson Power Supply. We are now warping some of the most significant innovations of our power supply into a neat package, which allows anyone to apply our technology into their existing gear and obtain instant and excellent results.

Why Low Noise Regulator?

Not only does our Super Regulator provide the basic function of a standard regulator (with a much lower noise level) it also incorporates a noise filtration network that will screen out a wide bandwidth of unwanted noise from upstream. This will leave the output power stable and noise free. When clean power is supplied to the rest of the circuit, your equipment will perform to their full potential. You will have overall improvement that is not limited to any particular section of the sound spectrum.

For example if you apply our Super Regulator to a typical CD player you will be able to hear a lot more micro detail that was once muddied by white noise. You will also find bass improvement with better control and definition because now the regulator can recover faster from large current draws. You can also expect to hear a more open sound stage as many of the hidden details will now appear, along with the rest of the information to form a more three dimensional sound stage.

Construction

Each Burson LNR is constructed from more than 17 components that includes 8 transistors, top quality DALE resistors, Evox MKP Caps etc. We hand solder each of them together onto a PCB board that is less than the size of a 50c piece. Last but not least we match it with a heatsink for bulletproof stability.

Some of you may wonder “Why Burson LNR does not use ICs to simplify the circuit?” as most of the biggest DIY brands are proudly showcasing their own Integrated Circuit (IC) based Super Regulators (and charging ridiculous margins for them). The answer is simple; ICs are just not good enough for Team Burson! From our HD Audio Opamp we demonstrated the shortfalls of op-amps (please click here to find out more) and the same principle applies when it comes to a Hi End power supply. We’d rather hand solder the 8 transistors instead of taking the easy way out.

What Improvement You Can Expect?

Once you have applied the Burson Low Noise Regulator (LNR), the noise floor of your music will reduce to minimal. You will find yourself in front of a much darker sound stage. Against this darker background, micro detail which makes music musical, once mucked by white noise will shine through to complete a more three dimensional sound stage. Against this darker background comes contrast, color, definition and a much happier audiophile…

You will be able to substitute the Burson LNR with the following module of conventional regulator:

Specifications

Noise:

• Module A & B: < 65 nV/SqrrtHz

Output impedance:

• Module A & B : <15m-ohm

Dimensions (Inc Heat Sinks):

• 40 x 40 x 30 mm (Module A & B)

• Weight: 15 gram

Installation

Installation of our Burson LNR Module LM78XX and Lm79XX is easy. De-solder and remove your existing regulator from your CD player or DAC and replace it with our Super Regulator with the same pin out.

However, LM317 and LM337 module require the following alteration to your existing circuit.
