This Power supply sources from 500 to 1,000 mA according the transformar and was found in a publication of the year 1958. The diodes can be now the 1N4004 and the transistor should be mounted on a heatsink.
This simple source of up to 1 A can supply voltages according to the secondary of the transformer, in this...
This circuit is based on the voltage drop of the diodes in conduction, in the order of 1.6 to 1.7...
We found this circuit in Motorola's 1990 Linear Databook. The component used is unusual. The...
