Re: Amplifier LM358—classical circuits

Thank you for all your advice, I just want to know the general ideas about these circuit schematic diagrams. Because I think these are useful if they are improved and bring some important parameters in specific examples. And it's like someone give you an idea to bring together all the individual par...

Amplifier LM358—classical circuits

Recently, I saw a article about amplifier LM358 with 24 classical circuit, it lists so many circuit schematic diagrams, but without specific description of each circuit. I have a little confused, I try connecting the author to get some simple summary of these diagrams, but he said it transmitted thr...

Re: How to tell it is good?

Thanks a lot for helping me, I made it for my interest, whatever temporary holding it, but I want to try because I am a complete newcomer to the electronic field. And now to be serious, for the circuit, I have checked the datasheet of whatever electronic component I used, I chose the LM350 because i...

Re: How to tell it is good?

dual 9V battery is the primary supply, and the Output voltage range is 35, 4.2 V, the resistance of potentiometer is 10k. Maybe I missed something when I connected the components with wires.

How to tell it is good?

I want to make a multiple voltage regulator, the goal was to make a variable power supply and make it as compact as possible. I know there are many other voltage regulator projects out there, but I wanted to make mine to suit my needs. My material includes dual 9v battery terminal, mini digital volt...
