    Very cheap device, currently the cheapest voltage regulator on DX, AFAIK. Very small so you can fit it almost anywhere. Very energy efficient, draws almost no power when the output is unconnected. Easy to set the exact output voltage (comes preset to about 12 V).


    I can't think of any so far.


    I have bought two of them to create a power supply to a standard hard drive that needs +5 and +12 V. As a source I have used a notebook AC/DC with 19 V output. So these two regulators convert the 19 V to 5 V and 12 V. It works perfectly.


    Will be buying more of them in the future.
