*The capacitor between the FB0 and VOUT pins and capacitor between the OERRAMP pin and GND (the capacitors
shown inside the broken lines in the diagram) are used for phase compensation. Their capacitance is intended to stop
oscillation when oscillation is caused by the status of the output capacitor. As such, they can be left open under normal
circumstances.
