https://devzone.nordicsemi.com/f/nordic-q-a/5698/voltage-regulator-recommendations-for-nrf51822Hello All, I am not an electronics engineer and have less experience with hardware. Posting here on behalf of my design engineer for help In our nRF51822 based device, we would like to use a shunt regulator to regulate an external 5VDC power inputen-USTelligent Community 13Tue, 24 Feb 2015 10:34:06 GMThttps://devzone.nordicsemi.com/thread/19957?ContentTypeID=1Tue, 24 Feb 2015 10:34:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f1cd7c47-38d3-4e64-9ce6-f797d392f7c1Stefan Birnir Sverrisson<p>Hi</p> <p>I don&#39;t think we have such recommendation. I know that some customers were looking into low-power switching regulators to feed supply power to the nRF51, but they are perhaps not very low cost. I include the references that I have for that, in case you might find it useful.</p> <p><a href="http://nl.mouser.com/ProductDetail/Texas-Instruments/TPS62122DRVR/?qs=0zjllh%252bnl7a8WLuFj1Q8pA%3D%3D">nl.mouser.com/.../</a></p> <p><a href="http://para.maximintegrated.com/search.mvp?fam=stepdn&amp;958=Internal&amp;tree=powersupplies">para.maximintegrated.com/search.mvp</a></p> <p>someone was also looking into something from <a href="http://www.micrel.com/">micrel</a></p><div style="clear:both;"></div>
