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

Part Number: UA723 Other Parts Discussed in Thread: LM723 , Hallo,
we were using the LM723, which is now obsolete. Now we trying to get a replacing part for the LM734.
The US723 seems to have some problems with the internal Zener diode reference. (see Link…
Part Number: UA723
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!
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,

Part Number: UA723 Other Parts Discussed in Thread: LM723 , Dear, Sir.
My customer was used LM723 -55 to 150 deg.C product for their systems.
Unfortunately it is impossible to purchase now.
Their system temprature range is -10/-5 to 70/85 deg.C, so they…
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…
Hi Jared,
I looked into this further and I was able to locate the modern, active equivalents for this device. So yes, they are still active and being sold. From the datasheet you linked:
