Found in a 90s Silicon Chip documentation, this circuit provides a current of 3 A and the voltages range from 0 to 20 V. The integrated circuit and the transistor must have heat sinks.
This circuit is from an old manual, but can be easily assembled as the integrated one is still...
The simple transistor test shown in the figure can be powered by a 9V battery. The test is for...
This regulator can use BD'136 as the main transistor and as a reference next to a BC548 zener. The...
