Do I need a voltage regulator in this circuit?

Hi,
I am trying to build a portable usb charger the outputs 5V when input is 1.5 or 3 Volts. I found this step up converter: goo.gl/RAV9dC
The spec for the converter state that the input voltage is 1V to 10V, and the out put Voltage is -1.5V to -10V and 3V to 10V. I frankly don't know how to interpret this information.
It seems to me that by inputting 1.5V, the output will be 10V. So I am wondering if am right, and IF I am, then do I need to put in a 5V voltage regulator in the circuit?
Thanks!

well it is a voltage doubler so if you put 1.5 volts in you only get 3 volts out and there is little you can charge at 10 ma.
No if you put in only 1.5V then your getting out only 3V.

Have a look at the Minti Boost from aidafruit. It's open source so you can get all the files on it and how it works. This will go a long way to helping you design your own.
