https://devzone.nordicsemi.com/f/nordic-q-a/121939/npm1300-ldo-quiescent-currentHello, I&#39;m evaluating the nPM1300 for a battery powered project. What is the quiescent current of the LDO? And is there an output current vs dropout chart?

I assumed the LDO is disabled for this condition. Can you confirm if the test condition for the 800nA spec includes LDO turned on?<br /><br /><img style="max-height:240px;max-width:320px;" title="" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1748870204000v4.png" alt=" " /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/537675?ContentTypeID=1Mon, 02 Jun 2025 13:08:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:65d569f3-033e-4d3b-a5c5-43ae084a36a9Hieu<p>Hi lewisleman,</p> <p>The quiescent current for Ship and Discharge mode are provided in <a href="https://docs.nordicsemi.com/bundle/ps_npm1300/page/product_overview.html#ariaid-title9">section 3.7, Electrical characteristics, of the&nbsp;product specification</a>.
