I have been asked to make a presentation on LM 723 as High Voltage High current regulator and high voltage low current regulator(I know the ic is way too old but its in our university syllabus so I have to do it.) So I wanted to know the electronic systems where 723 was used as HVHC, HVLC and LVHC voltage regulators. I looked everywhere on the internet but I couldn't find where they were used.

Here High Voltage High Current refers to an output of 7-35 volts and a load current greater than 150 mA High Voltage Low Current refers to an output of 7-35 volts and a load current up to 150 mA Low Voltage High Current refers to an output of 2-7 volts output and a load current greater than 150 mA.

  • \$\begingroup\$ You will not find where the LM723 is used because you'd have to have a searchable database with components used in every know product. Most manufacturers don't share this information (what would be the purpose?) so indeed, this is an impossible task. Your best bet is to look at the datasheet to see example schematics. The fact that the LM723 is old is (in my view) completely irrelevant as students need to learn how such a regulator circuit works and those principles don't change over time. \$\endgroup\$ – Bimpelrekkie Apr 16 at 9:51
  • \$\begingroup\$ @Bimpelrekkie the reason I included the fact that this is low because the last time I asked someone came commenting it is an old IC so decided to mention it in the start itself so no one comes to comment that again. If not appliances then can you tell the basic circuit where 723 was used as HCHC and HVLC \$\endgroup\$ – Bojack Horseman Apr 16 at 9:55

  • \$\begingroup\$ Just Googled lm723 power supply. Should be enough hits to get you started. Had you put the relevant info in your first post you probably would’ve got a better response. \$\endgroup\$ – Kartman Apr 16 at 10:20
