Aspects of the disclosure provide a circuit having an amplifier and a load current based control circuit. The amplifier is configured to detect a difference between a feedback voltage and a reference voltage, and control, based on the difference, a pass device to regulate an output voltage for supplying power to load devices. The feedback voltage is indicative of the regulated output voltage from the pass device. The load current based control circuit is configured to sense a load current output from the pass device to the load devices and generate a control signal to adjust a compensation capacitance based on the sensed load current to adjust a zero frequency of the circuit.
