A voltage regulator () is formed to generate a compensation current to flow when an output voltage of the voltage regulator () exceeds a compensation value. The compensation current is at least equal to the leakage current of the output transistor ().

Method of forming a low quiescent current voltage regulator and structure therefor

An multi-stage error amplifier () of a power management system () is formed to insert a zero to compensate for a high frequency pole that could cause unstable outputs at some output current levels. The error amplifier () includes a feed-forward block () that isolates the capacitor () from other signal paths to facilitate low noise and high efficiency operation.
