Abstract:
1. A voltage regulator comprising: a first FET having a first source coupled to an input terminal for receiving a voltage to be regulated, a first drain coupled to a first output terminal for providing a first regulated output voltage therefrom, and a first gate; a second FET having a second source coupled to the input terminal, a second drain coupled to a second output terminal for providing of a second regulated output voltage therefrom, and a second gate; a current source providing a current drive to the first gate and other than to the second gate in a first mode of operation and to the second gate and other than to the first gate in a second other mode of operation, the current source responsive to the first regulated output voltage in the first mode of operation and the second regulated output voltage in the second other mode of operation; and, at least a switch for switchably selecting between the first mode of operation and the second mode of operation.
