TPS7A4700 low noise LDO regulator PCB

[nautibuoy]

I have a few of the later blue versions of these regulator boards available if anyone is interested? They're unassembled (wrt to the through hole components) and unused.


PM me id interested.

All sold now.

Hi Ales,
how can I get your TPS7A4700 regulators? I need some 4 pcs.

Regards

Ales stopped selling these and has been quiet for quite a while.

I've had good results with these regulated supplies, which might suit your requirements?

As is typical for these types of supplies the specs are copied from LDO datasheets. Not based on measurements of actual devices.

I'm not sure of the point you're making, there was no suggestion to the contrary and I simply reported having good results.

My point was only that it would be better to show real measurements as reaching datasheet specs requires quite a lot of effort. It does not happen automatically.

if you want i can send you a board for free and you can post your measurents.

Sorry, but I think designing, implementing and selling these kind of devices without measurements is a flawed approach. How would you improve your products based on my measurements?

Why do you believe I need to improve it (particularly the TPS7A4700 board I've been selling since 2016)?
You claim that the specs of my boards are incorrect (copied from LDO datasheets) but can not prove it, and I think it is a "flawed approach". I have measurements from my client (measured at the UWA metrology group, for example). I have received repeated orders from many laboratories and universities (like the National Institute of Standards and Technology, Jet Propulsion Laboratory, the Large Binocular Telescope Observatory) and i believe it is a much more valuable evaluation.

I did not claim that the specs of your boards are incorrect but they are copied from LDO datasheets. If you have measurements why don't you use those instead?
