Abstract:
A low-dropout voltage regulator (LDO) apparatus is disclosed. In an embodiment, the LDO apparatus includes a voltage input connectable to a power supply, an error amplifier coupled to the voltage input and configured to receive a reference signal and a feedback signal and to generate an output control signal dependent on the reference signal and the feedback signal, and a pass transistor coupled to the error amplifier and configured to receive the output control signal of the error amplifier and to provide an output current dependent on the output control signal. The LDO apparatus further includes a detection circuit coupled to the voltage input and configured to provide an output signal on its output and a bias generator coupled to the output of the detection circuit and configured to provide a bias current on a bias input of the current adjusting circuit of the error amplifier.
