This regulator can be controlled by a logic signal. The circuit is from an Electronics Now from the 90s. Note that the switching transistor is before the integrated circuit.
The purpose of this circuit is to increase the selectivity of receivers with ferrite antennas. The circuit...
This solid-state relay circuit (SSR) or shield is from a 1995 Electronics Now. With it we can...
