Low noise Super High Current DC +4V to +30V and 50 similar items

Note on 4 May 2020 : The boards are now in green. This listing is a bare board of a super heavy duty power supply making use of five pieces of popular LT1083CP low noise regulator IC ( Alternatively, LM338 can be used too, but the LM338 has a package of TO-220 and different lead pitch so the legs need to be stretched during soldering). LT1083 family has been famous as a low noise low impedance design being used in audio circuitry like DAC circuitry , filament powering, to name a few. LT1083CP has a current rating of 7A. Thus the theoretical maximum current rating is 35A. For practical application with massive heatsinking a continuous current of 20A is achievable. The board allows an adjustable voltage range from DC +4V to +30V( single rail) by the on-board trimming potentiometer. The board allows direct mounting of LM1083CP on the board and massive heatsink on the LM1083CP. Operating voltage : AC 5Vx2 to 30Vx2 PCB dimension : 150mm x 122mm. Board thickness : 1.6mm . Board color : Blue. PCB finishing : 75um copper thickness( four times normal thickness !) with gold plating surface. Both side has solder mask coated for maximum durability.
