This circuit is ideal for creating a source that allows the use of automotive power devices on a bench. Transceivers, amplifiers, and other equipment can then be powered by the power grid. The regulator used an uA723 which consists of an integrated specific for this function. The 2N3055 transistor that has the emitter in the 0.065-ohm resistor must be mounted in an excellent heat sink. The 0.065-ohm resistor must be wire with good dissipation.
