Abstract
A voltage regulator control circuit includes a transistor input controller. The transistor input controller forces a slew control signal on its slew control output to a state responsive to a change in a load condition and forces an ON signal to a state on its first transistor control output. A first transistor has a first control input and first and second current terminals. A second transistor couples to the first transistor. A driver has a slew control input, a driver input, and a driver output. The driver input couples to the first transistor control output. The driver output couples to the first control input. Responsive to a first logic state of the slew control signal and a first state of the ON signal, the driver provides a higher current to the first control input, and responsive to a second state of the slew control signal and a first state of the ON signal, the driver provides a lower current to the first control input.
