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.
This source can supply currents up to 1 A. The circuit is from Motorola's 1993 Linear Interface ICs....
The purpose of this receiver is to monitor the signal from a nearby transmitter. It was published in an...
In the figure we have a symmetrical power supply stabilized by a zener diode. Transformer and...
