24VDC Supply to 5VDC

I have a 24VDC supply which needs to be lowered in my sub-circuit to 5VDC to power my Arduino and Quadrature encoder? What is the "standard" (if any) way of accomplishing this?

Switching DC/DC stepdown (buck) converters are preferred over linear regulation with that much drop.
Pololu has a whole range, with proper specs.
This one might be ok.

Plenty of <$1 clones with free shipping on ebay.
Leo..

Thanks for the reply!

Would a Switching Regulator also work?

A switching buck converter is a switching regulator

Oh hahaha

Here's a PS I made with an OKI 78.

There are lots of ready made modules like this on ebay.

Or.. you can also design your own.

I ve been using the mc34063 switching IC and there are lots of design tools on line.
