LINEAR VOLTAGE REGULATING CIRCUIT ADAPTABLE TO A LOGIC SYSTEM

摘要

A linear voltage regulating circuit adaptable to a logic system is disclosed. A first linear voltage regulator receives an input voltage and a first reference voltage. A second linear voltage regulator has a load driving capability lower than the first linear voltage regulator, and the second linear voltage regulator receives the input voltage and a second reference voltage. An output node of the first linear voltage regulator and an output node of the second linear voltage regulator are directly connected at a single common output node. A single common capacitor is connected between the common output node and a ground.
