Re: And they don't make noise

LDOs are certainly very simple devices to use them in design compared to the switching regulators. There are certainly lot of them which are must have in the designs as per the need.

I get a good chuckle over TI's use of the TPS prefix in their regulator lineup.  I have the cover sheet for the TPS54310 data sheet pinned up on my cube wall. Bill Lumbergh would have loved this - a genuine TPS report.

I agree with your statement about LDO noise vs switchers--but some of the newest switchers are extremely low noise and may be low-enough for your application--don't rule them out too soon!

In a low-level analog environment the LDOs keep the supply nice and clean.  Swiitchers on the other hand scream like a banshee.  Just try scope probing those little analog signals with that switcher howling away.


Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
