Abstract

An alarm based upon the voltage across a linear regulator's pass transistor and the regulator's load current alerts operational circuitry which obtains power through the regulator when the voltage across the pass transistor may be insufficient for proper voltage regulation. The alarm's trigger voltage is adjusted in response to variations in the regulator's output current.
