I am trying to power a micro air pressure pump similar to the one seen here:
http://www.alibaba.com/product-detail/micro-battery-pump-diaphragm-air-pump_60216515523.html
The specific one I have is 3V, 320mA. I want to power the pump using a power supply from sparkfun, (and eventually a battery 3.7V, XXXX mAH):
https://www.sparkfun.com/products/13032
I need to step down the V to ~3V from the selectable 3.3V from the power supply. I am using an XC6210 LDO regulator:

I t should be more than adequate with 700mA - 800mA output I measure roughly 3V output from the LDO regulator @3.3V input but the micro air pressure pump is not turning on. What am I missing?
