Circuit Project Electronic

Today a friend comes to see at a house lead electronics old equipment come to amount of. He consults me that what is set equipment should build electronics project ? good. I then advise that try build DC Supply adjustable Voltage Circuit. all right by can fine voltage [...]

1.2V - 12V with regulated current limiter through resistors
Person see the website wants DC Volt adjustable Regulate 1.2V to 12V current 1-2A sizes at the first stage me think will choose the circuit that use IC LM317. But he tells have IC LM723 the many. Then [...]

This is the schematic of the 30V/2A power supply I use in my own lab.It may look very complex, but it really isn’t very difficult to understand: it uses only the knowledge we’ve learned in the previous lessons.
The top part looks like the power supply we built in Lesson 7: the transformer L1 transforms the [...]
