Abstract:
1. A voltage regulator comprising: a current source having a first terminal coupled to a reference voltage terminal and a second terminal coupled to a voltage input (Vin) terminal, the reference voltage terminal for being connected to a component for creating a reference voltage; an amplifier having a first input terminal coupled to receive the reference voltage, the amplifier having a second input terminal coupled to an output voltage (Vout) terminal for receiving an output voltage of the regulator; the amplifier having a first power supply terminal coupled to the Vin terminal; the amplifier having a second power supply terminal; and an output circuit controlled by an output of the amplifier for causing an output voltage at the Vout terminal to substantially equal the reference voltage, the second power supply terminal being configured to allow a user to couple the second power supply terminal to either the Vout terminal, system ground, or another voltage in order to provide a sufficient voltage across the first power supply terminal and the second power supply terminal during operation to allow the amplifier to operate properly to achieve output voltage regulation.
