Abstract:
A low-dropout (LDO) regulator is provided. The LDO regulator comprises a first circuit operating as a closed loop control system. The first circuit is configured to control a voltage at a first node such that the voltage at the first node is substantially equal to a specified regulator output voltage. The LDO regulator comprises a second circuit operating as an open loop control system. The second circuit is configured to increase the voltage at the first node when a current flowing through a load changes from a first current to a second current. The first current is substantially equal to 0 amperes.
