If you will use a NXP board as reference for your design with an external PMIC you may use the ldo-bypass option as well.</P><P></P><P>There is a bit more information on this topic on page 67 of Application Note 4579:</P><P></P><P><A class="jive-link-external-small" href="https://community.nxp.com/external-link.jspa?url=http%3A%2F%2Fwww.nxp.com%2Ffiles%2F32bit%2Fdoc%2Fapp_note%2FAN4579.pdf" rel="nofollow" target="_blank">http://www.nxp.com/files/32bit/doc/app_note/AN4579.pdf</A></P><P></P><P>I hope this information helps!</P><P></P><P>Regards,</P></BODY></HTML> Tue, 06 Sep 2016 21:25:57 GMT https://community.nxp.com/t5/i-MX-Processors/IMX6Q-LDO/m-p/595231#M89413 gusarambula 2016-09-06T21:25:57Z
