          <div>In systems where there is, say, a 24VDC power bus and you

            $17 seems like a lot for a drop-in replacement for a 7805
            voltage regulator, until you realize that the sink/fan/board
            real estate/ventilation holes/etc to remove the heat from
            the 7805 would cost way more than that.  </div>

    This is better/cheaper for 5V 500mA from 6.5-36V:

    <br>
    And the big brother for 1000mA:
    <a class="moz-txt-link-freetext" href="http://www.digikey.com/product-detail/en/V7805-1000R/102-2178-ND/2352137">http://www.digikey.com/product-detail/en/V7805-1000R/102-2178-ND/2352137</a><br>
