https://devzone.nordicsemi.com/f/nordic-q-a/67817/reg0-output-vdd-rages-from-1-8v---3-3v---current-driving-capabilityHi, In my project, I am using High voltage mode [VDDH] in this case automatically REG1 [LDO] will be enabled. But my question is as per the datasheet i understood that even REG0 [LDO] will be active in this case with output range equal to VDD, can ien-USTelligent Community 13Fri, 30 Oct 2020 09:36:54 GMThttps://devzone.nordicsemi.com/thread/277763?ContentTypeID=1Fri, 30 Oct 2020 09:36:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8d5540ac-3ef6-43e4-b23a-6bc1f0a618ecketiljo<p>You can find it here:&nbsp;<a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/power.html#unique_1179047869">Regulator specifications, REG0 stage</a>. The extra current you can draw from REG0 depends on how much power the radio delivers. A 8 dBm, you can dram max 5 mA extra from REG0 and at 4 dB or less, max 25 mA.&nbsp;</p><div style="clear:both;"></div>
