Abstract: An active leakage consuming module (1001) is to be added to an LDO regulator without modification of the structure of this latter. The module provides a low-power operating mode with reduced current consumption, without impairing an operation of the LDO regulator for higher currents output by said LDO regulator. The module comprises a leakage current path (54) and control means (40, 50) for conducting consumed current below a threshold out of a pull-down path of the LDO regulator.
