DC adjustable power supply high efficiency 0-50V 1A by CA3130-CA3086

Today I would recommend a DC power supply that can adjust voltage and current, another one circuit. It’s very interesting since is highly effective, devices not very. This circuit has special feature that can supply output voltage widely range is during 0.1V to 50V
With value of the load regulation changes not more than 0.005% between 0A to 1A.
-The stability of regulation, when change the input voltage, the criterion is 0.01%.
-The noise output signal under 250uV
-This circuit can provide an output voltage in a wide range by the number of IC-CA3130 by the input range is 0V.
-During the extension of the output voltage can not, by adding Q4 between this IC and transistor both series. This circuit has a high threshold makes the regulation is accurately high level. Darlington transistors T1/T2 and make a high enough flow. Q3 is the limited current output. When the VR1 fully anticlockwise, Q3 current limit around 0.6A. This current limit, it will not work When the VR2 rotate clockwise until it stops.
