Part Number: UA723 Other Parts Discussed in Thread: LM337L
The output voltage of uA723 will drift with time, some chips become larger, some chips become smaller, and there will be small jitter when changing( Note: The width of the time axis is 12 hours…
Part Number: UA723 Hi,
Could you please tell me how to calculate the current sense resistor value?
In my application the current limit is 1.25 Amp. @ 45 volts.
Thank you

What is the approximate voltage of the Zener Diode between pin 10, OUTPUT, and pin 9, Vz, on the µA723 voltage regulator?
I can't find he Zener voltage specified on the datasheet anywhere.
Thanks for any help!
Hi Waldemar,
I reviewed our internal archives, which only list the zener drift issue we have already discussed. In our catalog of datasheet corrections, there is nothing significant for the UA723. I scanned through our E2E posts and nothing else jumped…
Part Number: UA723 Hi Team, I just need to confirm. Are there any internal connections with the NC pins of the UA723? Or this pins should only be left floating or connected to ground? Thanks in advance.
Kind Regards,

Sakai-san,
It appears that the LM723H/NOPB is still Active and available for orders/shipment. Are you saying the customer needs a different package option?
Please note there are currently no plans to extend the temperature range of the UA723 device…
Part Number: UA723 I have a power supply with 3 UA723 chips in it. I would like to rule out the chips as the problem. How does one go about checking if the chips are "doing there thin"g properly.
The power supply is jumping between 3v and 5v, it is…
Part Number: UA723 I have used 723 (mostly T-100 and PDIP) parts in instrumentation systems and production designs for may years. In 2012 I used the part in two new designs. we completed out preliminary design validation process using PDIP pars successfully…
