ABSTRACT:
A dual output voltage regulator circuit is disclosed. The output voltage regulator has a first FET and a second FET. A current source responsive to the regulated output voltage provides a current drive to the gate of the first FET in a first mode of operation and to the gate of the second FET in a second mode of operation. Further, the circuit employs switches for switchably selecting between the first mode of operation and the second mode of operation.
