    摘要: A voltage regulation circuit is provided. The voltage regulation circuit regulates a level of a supply voltage provided by an automotive battery. The voltage regulation circuit includes a selector and an error amplifier. The selector receives a plurality of predetermined voltages and selects one of the plurality of predetermined voltages according to a control signal to serve as a first reference voltage. The error amplifier generates an error signal according to the first reference voltage and a feedback signal. The feedback signal is related to the supply voltage. The voltage regulation circuit regulates the level of the supply voltage according to the error signal.
