Abstract
During transient operation of a voltage regulator, the gate of p-channel MOS pass transistor may be pulled down during the transient period to cause excessive surge current. The surge current is limited by using the pass transistor as a current mirror during the transient period. After the transient period, the pass transistor resumes its role as an element together with a differential amplifier and a reference voltage in a feedback loop to regulate the output voltage.
