Abstract
A low-dropout regulator includes an error amplifier to provide a control signal, a first transistor, and a second transistor. The first transistor receives the control signal and has a source-drain path electrically coupled between a supply voltage node and a load, the first transistor to power the load in response to a voltage on the supply voltage node rising above an absolute value of a threshold voltage of the first transistor. The second transistor has a source-drain path electrically coupled between the supply voltage node and the load, the second transistor to receive the control signal in response to the voltage on the supply voltage node rising above a particular voltage.
