LM723 comes in metal can, DIP14 and finaly SOIC14 SMD package. Even though it comes in an SMD package it may be to costly in terms of PCB space. Hence the question one LM723 two rails. Yes there are many fine AD ..sorry LT regulators but the cost may be prohibitive. I guess if you do not ask...

Jan 6, 2019 · The basis of this Power Supply is a standard LM723 circuit with parts around it, that make's it a good Power Supply. (my opinion) Preliminary Specifications The Output current wil be 2-Ampere Max. Max output voltage 20V.

Nov 2, 2024 · I used a 2x12V/500mA transformer and L7812 and L7912 for powering the LM723 and the OpAmp. 2. I removed C13, C14, C15, C16. 3. I replaced C6 by 2x4700uF/63V in parallel. 4. BD139 replaced by D44H11. 5. BD911 replaced by 4xTIP35C, and 4x 0.1R/5W. 6. RV1 = 50k. 7. U2 replaced by TL082. 8. R23 replaced by a strap. 9. R9=22k, R5=22k in parallel ...

May 17, 2017 · Re: How do make a current limiting knob using LM723 for Linear Reg power supplies? « Reply #24 on: May 19, 2017, 11:35:12 am » The circuit diagram for the HY3002 has one obvious mistake in the drawing: the emitter of V26A should be at ground level.

Dec 10, 2022 · Google this: ua723 vs lm723 and it comes up with this from the ti support site: LM723C and UA723 are exact same devices. The LM version was designed by National Semiconductor and UA is TI's device . The LM version was designed by National Semiconductor and UA is TI's device .

Dec 4, 2020 · The LM723 is only used as reference and auxiliary regulator. Looks odd, but is not that bad. It is still the old way of adjusting the feedback divider for the set voltage - this works but results in a loop gain that depends on the voltage setting: …

Sep 27, 2016 · LM723 is not the best choice for control circuit of a bench power supply. The current limiter of the LM723 is very fast but not precise. Use it only for protection of the output transistors, not for precision current limiting. Look for the Philips PE1542 power supply schematics. That's a very good application of the LM723 for a bench power supply.

Dec 1, 2016 · I'm trying to design a split power supply with a LM723, i already builded the positive one, my problem is in the negative part, i want a negative supply with a variable voltage of 0 to -15 volts with a current limiter of aproximately 1A, i don't need 1A exactly. I already saw the datasheet but it only gives a figure (figure 18 and figure 23 of ...

May 13, 2017 · I want to design lab power supply with the transformer rating of 30V , 5 ampere using LM317 or LM723. Because after rectification it would give around 42V Pulsating DC, So both these IC could Handle voltage around 40V. Hence this is the reason for adapting to these ICs. At the initial stage started with LT1084 and LM338.

Oct 21, 2024 · Re: LM723 and TL082 power supply « Reply #42 on: October 29, 2024, 03:45:39 am » If I connect the DSO probe to the PSU output positive or negative terminal, then the following waveform appears, and it is the same that appeared at the LM358 PSU.
