摘要
Certain aspects of the present disclosure are directed to a regulator. The regulator generally includes a source follower circuit and a low-voltage assist circuit. The low-voltage assist circuit generally includes a first transistor having a gate coupled to an output node of the source follower circuit, a voltage comparison circuit having a first input coupled to a source of the first transistor and a second input coupled to a control input node of the source follower circuit, and a second transistor having a gate coupled to an output of the voltage comparison circuit and a drain coupled to the output node of the source follower circuit.
