Claim Text:
1. A low-dropout (LDO) regulator comprising: a voltage reference circuit including a reference output for providing a reference voltage; a pass device including an input terminal coupled to a voltage input, an output terminal to provide a voltage output, and a control input; a feedback circuit including a feedback input terminal coupled to the output terminal and a feedback output terminal; an error amplifier including a first error amplifier input coupled to the reference output, a second error amplifier input coupled to the feedback output terminal, and an error amplifier output coupled to the control input of the pass device; and a control circuit configurable to selectively and independently adjust a first performance parameter of the voltage reference circuit wherein the first performance parameter comprises an output voltage, a second performance parameter of the pass device, a third performance parameter of the feedback circuit, and a fourth performance parameter of the error amplifier wherein the fourth performance parameter comprises a gain to digitally program a regulating function at the voltage output.
