Can the LP3943 source current as well, or only sink it? Answered
The link to the data sheet is here.
All it talks about is sinking current, so my guess is yes. I really wanted to use two of these to get a huge multiplexed array of LEDs, but one of them would need to be able to source the current, can it with the pins set high? If not, are there other ICs like this that can do so?
