ABSTRACT:
A saturation detection and warning circuit having an adaptive threshold voltage is disclosed. The disclosed circuit can also be used to detect the impending drop out of the low drop out linear voltage regulator. A clamp circuit that clamps the amplifier's output voltage at a voltage that is separated from the adaptive threshold of the saturation detector and warning circuit by a controlled offset voltage is also disclosed.
