How do make a current limiting knob using LM723 for Linear Reg power supplies?
<< < (3/9) > >>
Kleinstein:
The Phillips circuit looks very reasonably, and it is a tested circuit.

Just keep in mind that the pin numbers on the 723 are for the metal can. Today one will likely get the DIP version. So a little work finding the corresponding pins is still to do. The BDY20 used can be replaced by a more common 2N3055 or similar. The only thing a little confusing is finding out which pots are for setting the voltage / current by the user and which are just trimmers to set the voltage / current range.
oldway:
The trimpots are indicated by a sign that looks like a hammer, the potentiometers do not have this mark.
Gurumurthy:
Hi Sir,
        Can you please explain me this circuit. I cant understant Current Limiting Circuit.

Off topic....See videos of Dave about power supplies....

The OP is well known to spam the whole forum again and again with new thread on the same subject, when he didn't find any schematic that he likes, or no one answer him within a day. Looks like he doesn't like circuit that has too many components, or circuit that uses components that are not in his drawer.

Just read his past created threads.  :palm:

Also I did ask him a simple yet very important question on his 1st thread, but it seems like he ignored me.  :-//

I'm guessing that what he want is only a circuit that consist of max 2 transistors and few capacitors and a LM317 to build an adjustable 0-30V and 0-5A complete with with CC and CV feature.

Watch for his upcoming newly created thread as he doesn't like to use the 723 anymore.  :-DD
