We found this symmetrical regulator in a documentation from the 70s. The circuit uses components from that time, which are difficult to find today.
This circuit from an 80's publication also features low input capacitance. FET can be a modern...
This circuit was obtained from an American documentation from the 1980s. The T1 triggering...
The integrated circuit used in this project is not common today, but it can be implemented with more...
