This regulator with current boost and short circuit protection was found in the LM2931 manual that is used in this case. The integrated circuit is not very common today.
We find this circuit in the 80's own component manual itself. The characteristics of the circuit...
We found this amplifier with high input impedance and low capacitance, using FET, in a...
This circuit was obtained in a 1979 magazine, but it can be easily assembled today, as the...
