Hello,I've been using a voltage regulator (which has a heat sink) to try and convert a 12V power supply into 9V to power a few motors. I need a little over 1A of current. However, the current seems to be maxing out at about 0.6A when I use the voltage regulator. The motors with the same circuiting work fine when I use a 9V supply with a max of about 1.2A and don't use the voltage regulator. Does anyone know what the issue could be here? This is my first time using a voltage regulator. Thanks
Have you got the bypassing capacitors that the spec sheet recommends on the 7809?
Please indulge me with a question slightly OT.... if the 78xx spec sheets recommend certain caps, why don't they just build them in? (Implication of not doing so is that there are cases where no / different caps are better?)
