Are buck regulators DC isolated?

I need to build a small ± power supply supply to drive analog (opamps and the like) circuits. I would love to use two of your small (300ma) buck regulators in series to give me my ± 5V supply. This would only work is the output voltage is isolated from the input. Do you know if the output of any of your regulators are isolated?

Hello.

None of the regulators have isolated outputs.

Jan,
I suspected as much but had to ask…

Thank you.
