https://devzone.nordicsemi.com/f/nordic-q-a/62697/nrf52840-reg0-reg1Hi everyone, I need your advice regarding the regulator configuration of nRF52840 I am designing my own PCB using Raytac&#39;s module MDBT50Q-1MV2 that carries on the nRF52840 SOC. I will supply the module from a regulated 1.8V line and thus VDDH =en-USTelligent Community 13Mon, 29 Jun 2020 09:31:30 GMThttps://devzone.nordicsemi.com/thread/257314?ContentTypeID=1Mon, 29 Jun 2020 09:31:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3209f7ff-0333-4600-8a11-d62517315f09ketiljo<p><a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/ref_circuitry.html">https://infocenter.nordicsemi.com/topic/ps_nrf52840/ref_circuitry.html</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/257073?ContentTypeID=1Fri, 26 Jun 2020 09:17:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c0ae2f33-b5a3-48e3-a750-8eb602848798Nikosant03<p>Thank you for your answer!!
