1.2V – 12V with regulated current limiter through resistors
Person see the website wants DC Volt adjustable Regulate 1.2V to 12V current 1-2A sizes at the first stage me think will choose the circuit that use IC LM317. But he tells have IC LM723 the many. Then of this circuit better which this easy circuit, use integrated number this circuit. And still use number transistor TIP41 0R TIP31 help enlarge current get about 1-2A fine VR1 for choose Volt follow want. The detail is other can see in the circuit has and original website http://www.elektroda.net/warsztatowe/zasilaczelabor.html
