+15 Volt 1 Amp Regulated Power Supply

+15 Volt 1 Amp Regulated Power Supply
The actual supply takes +20 Volt Dc through the dioda bridge or filter part. This can be given to pins 11 and 12 on ua723, and also for the collector  2N3055 series-pass transistor. All the output voltage will be sampled through R1 and R2, giving around 7 Volt relating to ground at pin 4. The reference terminal at pin 6 is linked right to pin 5, the noninverting input of the error amplifier. (more…)
