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 ?
