Abstract
A low-dropout shunt voltage regulator is provided, which includes a first current mirror module, a second current mirror module and an output module. A first terminal of the first current mirror module is electrically connected to the input voltage. The first current mirror module has high output resistance. A first terminal of the second current mirror module is electrically connected to a second terminal of the first current mirror module. A second terminal of the second current mirror module is electrically connected to a reference voltage. An output terminal of the output module is electrically connected to the third terminal of the first current mirror module. The output terminal and a first terminal of the output module are both connected to the second current mirror module. A second terminal of the output module is electrically connected to the reference voltage.
