Our pcb current consumption is less than 0.5mA . We use a 3.7v lithium battery, and the battery goes through voltage regulator LD6806 that has a low dropout voltage ,and its output is the main 3v3 supply of the circuit .
The problem is , that we start to suspect that this regulator, is consuming more current than expected for some reason , and so our pcb now consumes more than expected.
This might be stupid assumption, but how can you check on the data sheet, whats the current consumption-the unwanted current- of this regulator, that is added to the original circuit current consumption ?

On the datasheet look for "quiescent current" specifications.
You'll see on Table 10 (page 7) a series of figures for different conditions, and the largest listed is 250 uA (0.25 mA).
Also, graphs in Section 9.3, page 10.
