Multi voltage power supply circuit. There is 2 Dual output, The 12V are +12V,-12V, Ground. And also the 5V are +5V, -5V, Ground. All 1A max.
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 5V 3A Switching Regulator circuit by LM2576-5.0 is simple switching power supply 3A step down regulator for power digital circuits. [...]
Here is circuit switching regulator 5V 5A for digital circuit. Use IC LM2678-5.0 is High Efficiency 5V 5A Step-Down Voltage Regulator This is good power supply, small size and do not hot.
This circuit has special feature that can supply output voltage widely range is during 0.1V to 50V. With value of the load regulation changes not more than 0.005% between 0A to 1A.
This is a USB 5V to 1.5V Step-Down Converter Circuit. When we use a Cheap MP3 Player which use only one 1.5V AA battery as its power supply.
Although the input voltage change between 5V and 13V but the output voltage is steady at 12V
Build 12V high current power supply, do not need PCB. We use a hammer and nail ! Why?
