Title: GENERATING THE UNDER VOLTAGE PROTECTION THRESHOLD
Abstract:
In described examples of a voltage regulator (300) having a regulated output voltage that droops down from a reference voltage (VDAC), an improvement includes generating a droop voltage portion of an under voltage protection threshold (IOCL*DROOP) by using a realization that an under voltage condition only occurs when an overcurrent condition (IOCL) exists, so that the droop portion includes the overcurrent limit value multiplied by droop resistance.
