Category FAQ

Q: Why choose linear over switching?

A: Linear supplies offer significantly lower ripple and noise (often <1mVrms), which is critical for sensitive electronics that might be affected by switching interference.

Q: Are linear supplies less efficient?

A: Yes, linear regulation is less efficient than switching, but the trade-off is the highest possible signal purity for precision laboratory work.
