Abstract: The present invention concerns a low dropout (LDO) regulator of regulating an output signal, the LDO regulator comprising an input stage (15) and an output stage (17), the input stage being adapted to receive a reference signal (VREF) and a feed-back signal (VF) depending on an output signal (VOUT), and to output an intermediate signal based on the feedback signal and on the reference signal, wherein the LDO regulator further comprises a gain stage (16) having a given gain value, which is configurable and wherein the output signal is regulated based on the gain value of the gain stage and on the intermediate signal.
