This simple low current circuit was found in a Radio Electronics magazine from August 1960. The circuit does not use transistors in regulation, but only zeners directly.
For bench use, this circuit functions as a bistable safety switch. The circuit is from a Radio...
The circuit shown is from Motorola's 1990 Linear Databook. Shaded components are optional. The...
We have here an ultra-simple amplifier stage of just one transistor, which can have some uses on...
