Patent ID: 7705575

Claim:
A voltage regulator system, comprising: a biasing module, operable to generate a first reference biasing signal using a first magnitude of power; a first amplifier module, operable to generate a first regulated control signal as a function of the first reference biasing signal; a second amplifier module, operable to generate a second regulated control signal as a function of a second reference biasing signal, the second reference biasing signal being generated using a second magnitude of power that is higher than the first magnitude of power; a standby detect module, operable to detect an operational condition being selected from a group consisting of a regular mode and a standby mode, and to output a selector input signal as a function of the operational condition; a selector module, operable to receive the first regulated control signal and the second regulated control signal, and to output a selector output signal as a function of the selector input signal, such that: when the operational condition is the standby mode, the selector output signal is a function of the first regulated control signal; and when the operational condition is the regular mode, the selector output signal is a function of the second regulated control signal; and an output module operable to receive a source voltage and to output a regulated output voltage as a function of the selector output signal, the output voltage being lower than the source voltage.
