So as your calculations say you are still safe enough with the mentioned current levels. I would recommend to move on with current LDO you have.&nbsp;<br />If you check Nordic reference designs, in one them that VDDH and VBUS are connected together , there is even a 2.2 Ohm resistor intentionally added to the VBUS path, together with a 4.7 uF cap to improve transient fluctuations.&nbsp;<br /><br /><br /><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1787224858522v1.png" alt=" " /><br /><br /><br />Best regards,<br />Ressa</p><div style="clear:both;"></div>
