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!
The circuit that see this is power supply 6V to 9V (Input 12V) of a calculator. That have preventing something through the circuit in. The part that perform to heal strong a picture uses the integrated circuit op-amp multi-purpose 741 numbers in the character comparator mode.
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.
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
This is a simple zener diode regulator circuit ,Simple Fixed regulator, multiple output voltage are: 12V, 15V, 30V
Simple Fixed DC Regulator using many zener diode. Good idea if use zeners!
Here is the 7805 5V voltage regulator datasheet the 7805 voltage regulator IC. They are designed to provide a constant 5V.
