SMPS in Linear Regulators
In a project of adjustable power supply that uses linear regulators (LM317, LM 350), it would be better to use as power source a conventional transformer or a SMPS?

Welcome, Tiloeco!
It depends on the application. Some audio and/or video equipment may have electrical noise issues when used with switching supplies.My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics. -

If it is a general purpose bench supply i would use a switcher, if it's for sensitive equipment (anything at the levels of a microphone or lower), it should be 100% linear. But using a SMPS then heating up a linear reg doesn't sound right IMO, why not an adjustable SMPS?A working TV? How boring!Originally posted by PeteS in CAComment

Re: SMPS in Linear Regulators
i did stuff like that back in school days, we used the reg trans and worked fine, but i guess implementing the SMPS has got to work... it may just not work properly on what you need, like japlytic mentioned.
