High current dual rail regulator PCB for power amplifier or bench power supply !

This is a bare PCB of a high current dual rail regulator board.

The circuit is design around popular and common regulator IC LM317 and LM337, with the current being boosted by high current pass transistors to get to a current as high as 5A( with appropriate heatsink size).

The regulator is good for class A amplifier power supply application, or to be used as a dual rail or single rail bench power supply for testing and evaluation of audio amplifiers. Since each rail of the regulator is standalone( sharing the same ground ), the regulator can also be configured as a single rail regulator.

Recommended input voltage : 9Vx2 AC to 22Vx2 AC

Output voltage : 9V dc to 30V dc , 5A max.

PCB thickness 1.6mm.

PCB dimension 73mm x 88mm

Copper thickness : 75um ( 4 times normal copper thickness !)

Surface finishing : Tin-plated, double-sided solder resist for maximum durability.
