Patent ID: 8902678

Claim:
A voltage regulator comprising: an input terminal configured to receive an input voltage; at least one output terminal configured to provide at least one output voltage; a first amplifier; a regulation transistor having a first conduction terminal coupled to said input terminal, a second conduction terminal coupled to said at least one output terminal, and a control terminal coupled to an output of said first amplifier; a voltage divider circuit comprising first and second terminals; said first amplifier comprising a first input terminal configured to receive a first reference voltage, and a second input terminal coupled to said first terminal of said voltage divider circuit and configured to receive a second reference voltage; said second terminal of said voltage divider circuit coupled to said second conduction terminal of said regulation transistor and configured to provide a regulation voltage thereto in cooperation with a current generated by said regulation transistor, the at least one output voltage being based upon the regulation voltage; and a compensation circuit coupled to said control terminal of said regulation transistor and configured to provide a compensation voltage in response to variations of the regulation voltage.
