nRF54L15 Optimizing Sleep Current – 100ms Spikeshttps://devzone.nordicsemi.com/f/nordic-q-a/119346/nrf54l15-optimizing-sleep-current-100ms-spikesHi everyone, I&#39;m currently working on a low-power application and aiming to minimize sleep current as much as possible. Thanks to some great advice I&#39;ve found on this forum, I&#39;ve already reduced the average sleep current to 0.9&#181;A , which is a significanten-USTelligent Community 13Thu, 27 Feb 2025 09:14:57 GMTRE: nRF54L15 Optimizing Sleep Current – 100ms Spikeshttps://devzone.nordicsemi.com/thread/525001?ContentTypeID=1Thu, 27 Feb 2025 09:14:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fdb523f1-1224-4de5-a268-cfc5281eee68Simonr<p>Hi</p> <p>These spikes is the LDO regulator&#39;s refresh mode. The regulator charges power on the capacitor from DEC4 and empties it when charged. This is perfectly normal, and as you can see the average current consumption is still &lt;1µA.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>RE: nRF54L15 Optimizing Sleep Current – 100ms Spikeshttps://devzone.nordicsemi.com/thread/524746?ContentTypeID=1Wed, 26 Feb 2025 08:31:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:746ffa60-d29d-4e0e-b6f8-489408c98c41lahn<p>Probably important Info: <br />Basically the nRF is only used for communication and is woken up via Interupt from an additional sensor</p><div style="clear:both;"></div>
