This circuit is based on a regulator component that consists of a transistor and zener in the same package. The circuit can be designed with the equivalent discrete configuration. The current is 200mA.
This two-port monostable of the 4001 was suggested by an article in the April 1988 Radio...
We found this circuit in a documentation from the 70s. Semiconductors are from the era and can be...
This circuit is from 1992 documentation. The transistor can be a TIP42 with a good heat sink for...
