Claim 13:
14. A system comprising:
an electrical load;
an output voltage terminal coupled to the electrical load;
a first amplifier having first and second amplifier inputs, a bias terminal and a first amplifier output, wherein the first amplifier input is coupled to a voltage reference, and the second amplifier input is coupled to the output voltage terminal;
a first transistor coupled to a supply voltage terminal and having a first control terminal, wherein the first control terminal is coupled to the first amplifier output;
a second transistor coupled between the supply voltage terminal and the output voltage terminal and having a second control terminal, wherein the second control terminal is coupled to the first control terminal;
a third transistor coupled between the first transistor and a ground terminal and having a third control terminal, wherein the third control terminal is coupled to the first transistor;
a fourth transistor coupled between an offset current terminal and the ground terminal and having a fourth control terminal, wherein the fourth control terminal is coupled to the third control terminal;
a fifth transistor coupled between the bias terminal and the ground terminal and having a fifth control terminal, wherein the fifth control terminal is coupled to the third control terminal;
a dynamic R-C network coupled between the first amplifier output and the fourth transistor; and
a buffer having a buffer input and a buffer output, wherein the buffer input is coupled to the output voltage terminal.
