A compensation circuit in a monolithic switching regulator controller being incorporated in a closed loop feedback system of a switching regulator includes an amplifier configured in a unity gain feedback configuration with a first resistor and including a non-inverting input terminal receiving the feedback voltage and an inverting input terminal coupled to a first terminal of the switching regulator controller. The compensation circuit further includes a first capacitor and a third resistor connected in series between an input terminal and an output terminal of an error amplifier of the switching regulator controller. The first capacitor and the third resistor introduce a first zero in the closed loop feedback system. When a second capacitor is coupled to the first terminal of the switching regulator controller, a second zero is introduced in the closed loop feedback system. The second capacitor is an off-chip capacitor formed external to the monolithic switching regulator controller.
