Voltage regulator with automatic accelerated aging circuit

摘要

A voltage regulator with automatic accelerated aging circuit (200) includes a comparator (202), a switched voltage divider (204), and a current-to-voltage converter (224). The voltage regulator (200) is implemented in an integrated circuit and monitors a power supply voltage provided to the integrated circuit. When the power supply voltage is within a first normal voltage range, the voltage regulator (200) provides a normal internal supply voltage to the integrated circuit. When the power supply voltage is within a second higher voltage range, the voltage regulator (200) automatically provides a higher than normal internal power supply voltage to the circuits of an integrated circuit for causing accelerated aging of the integrated circuit during burn-in reliability testing.
