Abstract:
A voltage regulator and method. The voltage regulator includes a first amplifier having: a first input couplable to a reference voltage; a second input coupled to a feedback path; a current mirror; first and second branches coupled to an input and output of the current mirror. A node of the second branch forms an output of the first amplifier. The voltage regulator includes a second amplifier comprising a transistor having: a first terminal couplable to a supply voltage; a gate coupled to the output of the first amplifier; and a second terminal coupled to an output of the voltage regulator. The feedback path is coupled to the output of the voltage regulator. The voltage regulator includes a compensation network having at least one passive component to reduce variations in an output current of the voltage regulator caused by the parasitic capacitance of the transistor and variations in the supply voltage.
