Abstract
A voltage regulator fabricated on an integrated circuit chip to provide regulated voltage for the chip assures that the integrated chip is operational before conventionally provided external regulated voltages are available. This enables the integrated circuit chip to be used to monitor the external regulated voltage supplies and prevents latch-up of the integrated circuit due to improper voltages being applied during power sequencing.
