Claim 5:
6. A regulator having an input and an output, the regulator comprising:
a first transistor having a first control terminal, a first current terminal configured to receive a band gap voltage and a second current terminal;
a second transistor having a second control terminal coupled to the second current terminal, a third current terminal coupled to the input of the regulator and a fourth current terminal coupled to the output of the regulator;
a soft start circuit including:
a capacitor having a first terminal coupled to the first control terminal and a second terminal coupled to ground; and
a switch coupled between the first terminal of the capacitor and a first source; and

a compensation circuit including:
a voltage source;
a third transistor having a fifth current terminal coupled to the voltage source, a sixth current terminal coupled to the first terminal of the capacitor and a third control terminal;
a fourth transistor having a fourth control terminal, a seventh current terminal coupled to the voltage source and an eighth current terminal connected to the fourth control terminal;
a first resistor connected between the third control terminal and the fourth control terminal;
a capacitor connected between the third control terminal and the sixth current terminal;
a first current source connected between the sixth current terminal and ground; and
a second current source connected between the eighth current terminal and ground.
