This stabilized source can supply currents up to 700 mA and the output voltage is close to 15 V. a little less with the load. The power transistor must have a good heat radiator.
This high-gain digital amplifier uses general-purpose transistors. The supply voltage is logic...
We found this circuit in the March 1993 issue of Electronis Now magazine. The circuit uses common...
Using an LDR as a sensor and an operational amplifier this circuit was found in the Encyclopedia of...
