This circuit was suggested by Texas Instruments in a 1980s documentation. The transistor must be equipped with a heat sink. The transformer has 10 A secondary current.
In the figure we have the way to implement an Exclusive OR or XOR gate with CMOS or TTL...
The basis of this circuit is the 723, an old integrated circuit not easier to find these days. The...
This circuit is from old documentation, but the regulator may be 78xx series equivalent and the...
