https://devzone.nordicsemi.com/f/nordic-q-a/97490/about-nrf52820-vddHi Nordic： NRF52820 uses REG0 to control the voltage output of 2.7V. If VDD is used to supply power to external devices, how much current can it provide。 best regard！！ jermi 2023.03。09en-USTelligent Community 13Fri, 10 Mar 2023 01:07:58 GMThttps://devzone.nordicsemi.com/thread/414508?ContentTypeID=1Fri, 10 Mar 2023 01:07:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fa395ba5-78d4-40bb-a61e-9218fd27ce6bjermi<p>&nbsp;Understand, thank&nbsp; your reply。</p> <p>&nbsp; &nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/414425?ContentTypeID=1Thu, 09 Mar 2023 14:56:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:55a6acf6-fa0f-42d2-bba6-304f38b177f5Priyanka<p>Hi,</p> <p>Sorry I don&#39;t follow your question. Do you wish to know the current consumption at VDD when it is used to supply power to external circuitry, in high voltage mode of 52820?</p> <p>If so, it is not possible&nbsp;for VDD to supply power to external circuitry, in the 52820. This is possible only in the 52840.</p> <p>Best Regards,</p> <p>Priyanka</p><div style="clear:both;"></div>
