摘要: A voltage regulator may include an input terminal for receiving an input voltage and an output terminal for providing a respective output voltage, a regulation transistor having a first conduction terminal coupled to the input terminal for receiving the input voltage, a second conduction terminal coupled to the output terminal, and a control terminal coupled to the output of a first operational amplifier. The first operational amplifier may have a non-inverting input terminal for receiving a first reference voltage, and an inverting input terminal coupled to a first terminal of a divider circuit for receiving a second reference voltage.
