Indicated for powering circuits with operational amplifiers, this source was found in Popular Electronics. The output voltage depends on the transformer used, as well as the current.
The maximum current of this power supply is 2 A and the output voltage can be set between 6 and 24 V. The...
This circuit, published in the 1980s, can be applied to operational amplifiers of almost any type....
We found this circuit in the October 1992 issue of Radio Electronics magazine. The duty cycle can...
