Abstract

An internal voltage generating circuit down-converts an external supply voltage and changes a reduction in its output voltage level from the external supply voltage level as the external supply voltage increases. The internal supply voltage is kept lower than the external supply voltage by the constant value while the external supply voltage stays under a predetermined voltage. The reduction amount is increased in proportion to the external supply voltage while the external supply voltage is over the predetermined voltage.
