    Hi :)
    I have a 12v -> +/- 5v converter IC, datasheet here http://www.cui.com/pdffiles/VASD1-SIP%20series.pdf

    This particular IC needs to be loaded at least 10% (10mA) all the time.
    I'm using this to power some analogue switches at +/-5v, but they draw so little power, they are not going to load the converter up at full power, let alone when they are idling.

    Question is, can I connect a resistor between (ideally + and -, of 1kohm) + and COM of 500ohm, and - and ground of 500ohm?
    If I'm not completely missing the point, this would allow 10mA to heat up the resistor right?

    Can I use two resistors to do this?
    Can I make it even smaller by using one resistor, skipping COM?
