This be power supply variable regulator circuit, since 5V to 13V that current about 1A. By use IC LM7805 (3-Terminal 1A Positive Voltage Regulator) perform maintain one’s position voltage, be stable that 5V. And have op-amp IC number CA3140 , help fine decorate voltage go out can modify 5V to 13V from get, by use [...]
A very good and powerful Regulated Power Supply section was implemented by simply adding a PNP power transistor to the excellent LM317T adjustable regulator chip. In this way this circuit was able to deliver much more than the power required to drive two Mini-MosFet amplifiers to full output (at least 2Amp @ 40V into 4 [...]
The circuit is fairly standard of a linear supply, and the function of each part can be described as follows: TX1 is a center-tapped transformer which converts the line voltage from 120 or 240VAC to a lower value which can be managed by the filter circuitry. See note 1 for more details. Diodes D1-D4 rectify [...]
