This is microprocessor power supply circuit, 5V 3A by LM323K, for use in experiments such as logic circuit and/or Microprocessor types that use voltage 5V
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 Small 5-volts DC Regulator. without IC-7805. Using transistors are interesting. If you have an old transistor or want to save. It may be a good choice.
A good DC switching power supply circuit form old computer that not used. It has used powerful, durable and works great.
I collect these transformerless power supply circuit, use a capacitor instead, it smaller and lighter than transformer. There are circuits as follows.
If you want to a LM338 variable dc voltage power supply circuit during 1.2V to 30Vdc and can provide a current maximum to 5A.
it is protected the current over the limit that we define at about 100 mA.
This circuit acts rectifier the ACV signal.This circuit usually requires two op-amp, but this circuit uses only one op-amp.
