摘要：
An improved voltage regulator which can operate in a two-lead environment with a widely varying power supply is provided. The voltage regulator of the invention has an output circuit stage connected between a supply voltage and a reference voltage. A pass transistor, as one leg of a differential current steering stage, provides drive current to the output stage. A bandgap error amplifier is coupled between the reference voltage output and the pass transistor to shunt current from the pass transistor when the reference voltage varies from the desired voltage value.
