Urgently if you like me

hello, is that it’s good for regulators as a metal detector?

it is imperative to me 12v output voltage

thank you, thank you

The regulator can provide 12V output, but we would need to know more about your setup to know if it would work well. What do you need it to do and what is the input and desired output (voltage and current)?
