https://devzone.nordicsemi.com/f/nordic-q-a/4696/dynamically-changing-supply-voltageI have a follow-up to this question: devzone.nordicsemi.com/.../ We are interested in dynamically changing the supply voltage because our space-constrained design requires it. Specifically, extra board area for level translation components is not availableen-USTelligent Community 13Thu, 04 Dec 2014 22:08:45 GMThttps://devzone.nordicsemi.com/thread/16647?ContentTypeID=1Thu, 04 Dec 2014 22:08:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5dfee99f-e771-4740-b7f7-d393721aa9a0embedded_ee<p>Thank you!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/16646?ContentTypeID=1Thu, 04 Dec 2014 14:33:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:38514ee7-6e1d-4819-a926-b136df4d6e74Asbj&#248;rn<p>This information is not available in the nRF24LU1+ documentation. The slew rate isn&#39;t defined, but worst case if you change between voltages is that you will reset the chip. How fast you can change it is not a number we have available. I don&#39;t see any issues with what you guys are planning. If you are planning on sudden changes, then you would have to expect a reset on the chip.</p> <p>The 100 mV values are tests that we did on the radio interface if you have noise on the power supply. The performance of the chip will be the same if it runs at 2.0 V or 3.3 V as internal regulators provide the internal supply.</p><div style="clear:both;"></div>
