Claim 0:
1. A circuit comprising: a pass transistor drive circuit comprising an digital input, and at least one output configured to be coupled to at least one pass transistor; a digital feedback circuit having a first analog input configured to be coupled to the at least one pass transistor, and a digital output coupled to the digital input of the pass transistor drive circuit; and a continuous-time analog feedback circuit comprising a second analog input configured to be coupled to the at least one pass transistor, and an analog output coupled to an over voltage node of the pass transistor drive circuit, wherein the analog feedback circuit has a direct current (DC) gain greater than zero,
wherein a bandwidth of a first control loop comprising the digital feedback circuit is less than a bandwidth of a second control loop comprising the analog feedback circuit.
