Assignee: ANALOG DEVICES, INC.
Field: Control (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A voltage regulator circuit, comprising:
a reference input to receive a reference voltage;
a first error amplifier coupled to the reference input, the first error amplifier comprising an output indicative of a first difference between a representation of the reference voltage received from the reference input, and a representation of an output voltage of the voltage regulation circuit;
a pass device coupled to the output of the first error amplifier, the pass device arranged to supply an output of the voltage regulation circuit;
a second error amplifier coupled to the reference input, the second error amplifier comprising an output indicative of another difference between a representation of the reference voltage received from the reference input, and another representation of the output voltage of the voltage regulation circuit;
a shunt device coupled to the output of the second error amplifier, the shunt device arranged to provide a temporary current pathway during an unwanted transient condition to change current provided to a load connected to the output of the voltage regulation circuit; and
wherein the second error amplifier provides at least one of a propagation delay duration that is shorter in duration, or a bandwidth that is wider, in comparison to the first error amplifier.
