This circuit uses a feedback integrator. We found it in Ferranti's transistor manual from 1974. Transistors are general-purpose types at the time.
The power supply shown in the figure provides output voltages in the range of 1.2 to 25 V with...
The components used in this regulator project from an old documentation are not very common today....
The circuit shown in the figure makes use of an LM3909, a low consumption and low voltage IC. The...
