Voltage downconverter circuit capable of reducing current consumption while keeping response rate |
摘要 |
In a VDC circuit, a differential amplifier compares a first reference potential with an internal supply potential to generate a control signal according to a result of the comparison. A constant current source transistor receives at its gate a second reference potential supplied through a path different from that of the first reference potential to operate for controlling an operation current value of the differential amplifier. A drive transistor changes conductance between a node for outputting the internal supply potential and a supply potential according to the control signal.
