https://devzone.nordicsemi.com/f/nordic-q-a/120826/tx-max-power-impacted-if-usng-1-8v-on-vddHi Nordic engineer I am evaluating a project based on nRF52840 and there is a question need to be confirm before schematic design start. Due to limitation of power resource , I can only provide 1.8V as power supply for nRF52480. I checked the datasheeten-USTelligent Community 13Tue, 22 Apr 2025 08:04:11 GMThttps://devzone.nordicsemi.com/thread/532279?ContentTypeID=1Tue, 22 Apr 2025 08:04:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:573b75c1-ca7f-4d7d-b5b3-f5710f692094huangsong<p>Hi Ketiljo</p> <p>Thanks for explaination~<span class="emoticon" data-url="https://devzone.nordicsemi.com/cfs-file/__key/system/emoji/1f44d.svg" title="Thumbsup">&#x1f44d;</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/532257?ContentTypeID=1Tue, 22 Apr 2025 07:06:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:eabbab34-cc0a-4486-899e-d3178209e488ketiljo<p>The radio has a internal regulator and operates below 1.8 V so the TX power is unaffected by the supply voltage.</p><div style="clear:both;"></div>
