Hi!
Today I got an Arduino Mini.
I found in the LP2985 datasheet that there is a flow from output (+5V) to ground via 2 resistors.
How big is that current?
Should I unsolder that tiny thing?
I found two 3 legged SMD parts (one on each side).
I havent found them on this page: http://arduino.cc/en/Main/ArduinoBoardMini
What r they doing?
R they using power?
Thx.
Bye

The LP2985 provides a regulated 5V output from an external power input, like 9V. You can desolder it if you can just power your board directly from an external regulated 5V source.
But I don't think it's necessary. Those two resistors inside the LP2985 are very high and do not waste very much current. The "ground pin current" (wasted current by the LP2985) is only on the order of 1mA maximum at 50mA load current (see page 6 of its datasheet, Ignd parameter).

ok - with "sleep mode standby" i get 600uA... 
thx
