Output current is controlled by the PMOS transistor, which in turn is controlled by the error amplifier.The plot shows that it takes time for the LDO to response to a load current step. The current initially comes for capacitor, hence the output drops. Once the LDO current equals the load current the output voltage stops decreasing. The LDO current then charges the capacitance. This overshoot happens because the compensation design. The plot shows that it takes time for the LDO to response to a load current step.
