Hello everyone. Please, can someone give me the name of a regulator that takes 130V DC as input and regulates to 5V DC at the output?

 

hi NG,
Welcome to AAC.
If you could drop the Vinput by a few volts, this may help you.

No NEARLY enough to go on!

Are you looking for an IC, or an off-the-shelf benchtop unit, or what?

If you only need a few microamps of current and the output tolerance isn't too tight, then a simple Zener regulator might be more than sufficient. But if you need tens of amps and the 5 V to be within 1% over temperature and operating point, that's a very different story.

What have YOU done to even determine what your needs are?

Have you even looked to see what kinds of regulators are readily available?

If not, go do both of those. It will at least help you better define what you need to accomplish, which will help us help you better.

Thank you so much engnr

 

If you are looking for self-contained modules, try searching for "DC-DC converters" or "battery eliminators".

Here's one that's not very expensive (but we have no idea what your budget might be). DigiKey has it for about $15.

Mean Well USA has a wide selection of converters.

 

If you meed no more than 2A, a generic USB phone charger will work.

I want 5V DC in ouput of regulator... | max input = 130 V DC and ouput = 5V

 

Repeating the same insufficient information you already gave is not helpful.

How much current do you need?

Since you insist that this is all the information you are going to provide, despite being told that it is nowhere near sufficient, then either use a cheap USB phone charger or a higher-end Meanwell SD-350C. Either satisfies all of the requirements you've specified.

There. Your question is answered.

No, it's to integrate it into the power supply circuit of a control board that I'm building. This regulator must have only 3 pins and take input (maximum voltage of 130V DC) and deliver to the output (a voltage of 5V DC)

At what current?!?!?!

You seem to be unable to grasp that there is no way to even attempt to provide any meaningful suggestions unless we know how much current this regulator needs to be able to supply.

Since multiple attempts to illicit that information from you have failed, I'm moving on to someone else. Good luck.
