https://devzone.nordicsemi.com/f/nordic-q-a/62284/nrf52840-maximum-peak-vs-continuous-current-from-vext-vdd-supplyHello, I am designing my second revision of custom hardware and am debating replacing my external regulator with the nrf52840&#39;s internal REG0 stage. I have read the product spec and noticed that maximum current supplied by the REG0 (IEXT) stage to VEXTen-USTelligent Community 13Wed, 10 Jun 2020 12:15:03 GMThttps://devzone.nordicsemi.com/thread/254251?ContentTypeID=1Wed, 10 Jun 2020 12:15:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7ddc3232-f70b-4d2a-8e3c-6d8557b8cdfcKaja<p>Hi,&nbsp;<br /><br /></p> <p>here is the answer:&nbsp;</p> <p>the total output current from REG0 counts and is specified to max 50mA. The limit accounts for continuos current, and peak current, when peak current duration is more than few us.</p> <p>Slight exceeding&nbsp;should not burn the device nor collapse the supplies and overall risk of malfunction should be moderate. However, as the device has not been characterized over 50mA, it&nbsp;is on users responsibility. &nbsp;<br /><br />Best regards,<br />Kaja</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/254014?ContentTypeID=1Tue, 09 Jun 2020 10:59:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:69ca4281-6a09-44c7-bb60-4e4f3583480dKaja<p>Hi,&nbsp;<br /><br />I have forwarded this internally, I will get back to you soon with an answer.&nbsp;<br /><br />&nbsp;Best regards,<br />Kaja</p><div style="clear:both;"></div>
