Abstract: An electronic device may include: a load and a voltage regulator coupled to the load and configured to provide a load current, where the voltage regulator includes a first and a second pass device coupled in parallel and configured to operate simultaneously. A method may include providing current to a load using a first and a second pass device coupled in parallel and configured to operate simultaneously, where the first device provides a first current corresponding to a high-frequency component and the second device provides a second current corresponding to a low-frequency component; in response to a decrease in a low-frequency component, causing the second current to decrease and causing the low-frequency component to increase; and in response to an increase in the low-frequency component, causing the second current to increase and causing the low-frequency component to decrease.

Abstract: In an embodiment, an electronic device includes a first amplifier having a non-inverting input configured to receive a reference voltage and an inverting input coupled to a first output node, where the first amplifier is configured to produce a first output voltage at the first output node. The electronic device also includes a second amplifier having a non-inverting input coupled to a ground reference level, and an inverting input coupled to the first output node via a first resistor and to a second output node via a second resistor, where the second amplifier is configured to produce a second output voltage at the second output node.
