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.

This is dual 15v power supply schematic, using LM7815,LM7915,and power transistor and zener diode for voltage stable voltage 15 volts positive and negative. [...]
In a normal circuit, the general LM350 regulator has a start voltage of 1.25V. But this circuit is special that start of 0-volts. We use only one IC and a few other components. So cheap and easy for you.
SEE! the 24V 2A power supply circuit for a 30w power amplifier or others circuits.
First choice of Fixed Regulator using family IC-78xx. It is easy to use, cheap, popular for a long time.
This is a 3A adjustable regulators using IC-LM350 that looks like LM317 Variable DC Power Supply, but high current higher 3A, adjust voltage 1.2V to 30V
This is LM317 voltage selector power supply projects can select output 1.5V,3V,4.5V,5V,6V,9V at 1.5A current. you can use as as battery, so saving.
This is the 0-30V,0-2A adjustable voltage and current regulator that developed from the cheap adjustable 0-30V 2A Laboratory DC Power Supply project using LM723 is used widely, for a long time.
