This variable voltage regulator circuit has a power stage capable of supplying currents up to 1 A. The power transistor must be equipped with a heat sink.
This configuration makes use of an integrated circuit of the time having been found in a 1976 NASA...
We find this circuit in a 1978 documentation. The circuit uses two inverters of a 4049 integrated...
This configuration is from a 1966 publication. However, with small changes in component values it can...
