Hi Alone173,
In the previous reply, I attached the following link in TI E-store. If you login your user information, you should be able to see the inventory availability on various parts, pricing, performance etc.

Hi,
The TL431 has a instability region as specified on figure 16/18 of the TL431 datasheet. It is important to use a capacitor that is outside of this region.
We have also made a app note to discuss this. If you need a low cost regulator for 2.5V…
Hi Tony,
In Texas Instruments we have 2 version of the LM4040 which can be confusing: LM4040 and the LM4040-N . The LM4040 does not have a TO-92 but the LM4040-N does. I believe you are looking at or have the LM4040-N in TO-92. The pin out for this…
Hi,
Is there a reason you are using the LM4041 for a 5V output?
I would use the fixed 5V output LM4040-N at 100ppm/C from -40C to 85C. This way there is no error from the resistors.
Since you need better temperature drift. I would recommend the…
Part Number: LM4040 Hello,
Figure 6 on page 32 of the LM4040-N datasheet shows input voltage step response for the LM4040-N-2.5: approximately 40 µs after input voltage is applied the voltage reference reaches its nominal voltage of 2.5 V. Does this…
Hi Claverie,
Thank you for the schematic. In your implementation you have a lot of passives to adjust and you are using a FET for high current even though only low current is needed. Have you tried implementing figure 16 or 17 from the LM4040-N datasheet…
Hi George,
The closest we have is the LM4040-N which can do 5V or 10V.
If you need the 6.9V then I would use the LM4041-N w/ external resistors as it can be adjusted to 6.9V with similar specifications.
Can you tell me more about the application…
lmp7702.pdf lm4040-n.pdf Good day Paul.
Yes, you may contact me on me email please.
I have just a few more questions and data sheets of a amp and U3 that i found in South Africa. Please see if these components are compatible.
Hi Mike, Are you aware of the LM4040-N? It is very similar to the LM4041, but instead of adjustable comes in a variety of fixed options, including 3V. The fixed LM4040-N 3V would remove the need for feedback resistors. The LM4040-N is available in the…
