Every electronic gadget primarily needs a D.C, power supply to energize it. It also forms the basic requirement for any constructional project. consequently there is a need to obtain multiple voltage values for cost...
message: Hi, i’m looking at building a power supply 0-35v ,0-100A adjustable cv and cc. I stumbled across your circuit drive-scr-thyristor-with-555 is there a link to describe what phase logic is required to complete the...
In this circuit the 12 DC, two wire is converted to three wire +5 and 0 and -5 dual supply useful for op-amps or other interface circuits. You could use 7805 and 7905 low...
This was a common way LM317 was used to get a stable power for small devices. It is still useful for learning and some blocks of the circuit are still used today in modern...
I will just explain part of this circuit. D9 and D10 provide a low cost -1.4 from -5 V. This is needed to reach near 0.00 for LM317 Min. setting. An LED also can...
This circuit uses a PNP Power Transistor TIP2955, you can use any other according to your current and voltage requirement. Look at R2 a 10 Ohm resistor, when the current in your load to...
This board provides 5 volt or 13.8 volt power. may be built up as a 5 v/13.8 v dual power supply. This board has LM317 and make a nice Laboratory bench supply. Thanks...
message: Hello, I want to know the single IC which can provide Both + V and -V from a single +Vin supply.. I need this for my dual supply opamp.Reply me as soon as...
