This is a 15V DC Regulator circuit at 400mA using IC-748 and 2N3055. Although it is an ancient circuit, but if you have the equipment ready. we may try to build it.
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.
Note: If you do not see the power supply circuit that you need. Please use the search box below!
When I need to use DC regulator power supply 18V 1A for the transistors pre tone control circuits.
Modify power supply source in old circuit PCB. I then build to is 9v regulated power supply circuit , that can give current 1 to 2Amp. Look 3 circuit below
If you would like to build Simple 3.3V Power Supply circuit for digital micro controller or esp8266. This circuit may be one way for you. It can power current at 1A maximum. We normally use common electronics parts, so easy and cheap.
Automatic nimh battery charger circuit that automatic cuts off. This project is good ways,Use AN4558 OP-AMP IC. Detect battery voltage when power is full.
This is Ham radio power supply circuit for Amateur radio CB/RF/VHF use 13.8V supply. It is good circuit with PCB low noise RFI elimination we use LM350T
