摘      要：According to the requirements of the bus terminal regulator,a linear regulator with 3-A source-sink current ability is *** use of the NMOS pass transistor and load current feedback technique enhances the system current ability and response *** method of adaptive zero compensation realizes loop stability over the whole load range for either source or sink ***,the transconductance matching technique reduces the shoot-through current through the output stage to less than 3μ*** regulator has been fabricated with a 0.6-μm 30 V BCD process successfully,and the area size is about 1 mm;.With a 20μF output capacitor, the maximum transient output-voltage variation is within 3.5%of the output voltage with load step changes of±2 A/lμ*** the load range of±3 A,the variation of output voltage is less than±15 mV.
