Abstract
An integrated circuit includes a voltage set input terminal, a current source, a voltage clipping circuit, and a voltage regulator. The clipping circuit receives a voltage from the terminal and supplies a voltage onto a reference voltage input of the regulator. The magnitude of an output voltage VOUT output by the regulator is the voltage on reference voltage input multiplied by the voltage gain of the regulator. The user sets VOUT by attaching an external resistor to the terminal. Current from the current source flows out of the terminal, and through the external resistor, thereby setting the voltage on the terminal. If the voltage on the terminal is between Vand V, then VOUT is a fixed multiple of the voltage. If the voltage is less than V, then VOUT is a predetermined VOUTMIN value. If the voltage is greater than V, then VOUT is a predetermined VOUTMAX value.
