Yeah that was my worry, However i think i'm going to take the risk. As the cheapest i can find them is from in the uk is from RS, ~30 pence each (+ shipping +a card handling charge as my order would be under £20)

Edit: the best ones from farnell is : http://uk.farnell.com/rohm/bu2jtd3wg-tr/ldo-fixed-2-85v-0-2a-ssop-5/dp/2342945

However the £20 pretax minimum order limit is a real problem for me
