A voltage source device for low-voltage operation which sources a desired voltage while minimizing variations in output voltage due to changes in temperature. The voltage source device includes a current source circuit having a temperature characteristic of (1/T)-a and a compensation circuit having a temperature characteristic that includes a term of -1/T, which compensates for the temperature characteristic of the current source circuit. The voltage source device also includes a voltage conversion circuit for converting the power supply current provided by the current source circuit into a power supply voltage and outputting it externally.
