Abstract
A low-dropout regulator comprises an output current branch (100) in which a first output driver (110) and a second output driver (120) is arranged. An input amplifier stage (200) provides a first control current (I1) to control the operating state of the first and the second output driver (110, 120). A current generator unit (300) provides a second control current (12) to operate the first output driver (110) in the second operating state and provides a third control current (13) to operate the second output driver (120) in the second operating state, when the first control current (I1) of the input amplifier stage (200) is below a threshold level.
Claims15
A low-dropout regulator, comprising:
- an output node to provide a regulated output voltage,
- an output current branch coupled to the output node, the output current branch comprising a first output driver and a second output driver, wherein the first and the second output drive are configured to be operated in a first and a second operating state, wherein the respective conductivity of the first and the second output driver is higher in the first operating state than in the second operating state,
- an input amplifier stages having an input side to apply an input signal and an output side to provide a first control current to control the operating state of the first and the second output driver, wherein the input amplifier stage generates the first control current in dependence on the input signal,
- a current generator unit to provide a second control current to operate the first output driver in the second operating state and to provide a third control current to operate the second output driver in the second operating state, when the first control current at the output side of the input amplifier stage is below a threshold level.
