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.
This configuration that appears elsewhere on this site was found in a Popular Electronics of the 1980s. The...
In the figure we have a small general-purpose amplifier with the LM386 integrated circuit and...
An interesting solution that can be provided in some cases is the one shown in the figure in which...
