This high current regulator with low voltage drop was found in the datasheet of the used integrated circuit itself. The transistor accepts an equivalent and must be provided with a heat sink.
The integrated circuit used is equivalent to the 555 and the transistor can be the BC558. R1 and...
We found this circuit in issue 10 of the Italian magazine Selezione Rádio of 1982. The circuit...
This circuit is from 1997 documentation, a time when the parallel port was the most common means of...
