In this library you'll find anything that has to do with power delivery, or making power supplies.
&lt;p&gt;Contents:
&lt;ul&gt;&lt;li&gt;LDOs&lt;/li&gt;
&lt;li&gt;Boost/Buck controllers&lt;/li&gt;
&lt;li&gt;Charge pump controllers&lt;/li&gt;
&lt;li&gt;Power sequencers&lt;/li&gt;
&lt;li&gt;Power switches&lt;/li&gt;
&lt;/ul&gt;&lt;/p&gt;
&lt;br&gt;
We've spent an enormous amount of time creating and checking these footprints and parts, but it is &lt;b&gt; the end user's responsibility&lt;/b&gt; to ensure correctness and suitablity for a given componet or application.
