If you are looking for a power supply circuit. Here may be the choice you need. over 150+circuits with PCB and easy to build, low price for a beginner.
An electronic device needs to use a power. We have a lot of power supply circuit. We recommend the example tag: (It may make you find the circuit easier.)Fixed voltage regulator :: 3-volts :: 5-volts :: 6-volts :: 9-volts :: 12-volts :: 15-volts :: Protection :: Transformerless :: Negative Power Supplies :: Dual output power supply :: Variable DC Power Supply :: 0-30V DC Power SupplyAdjustable DC power supplies :: Switching power supply :: High current :: High voltage :: Zener Diode Regulators :: Multi voltage regulated :: 7805 Regulator Circuits :: LM317 Circuits :: PC power supply circuits
and We love renewable energy, clean, and long with solar.
