For output voltages

≤ 1.2 V, a 22-µF output capacitor value is required to achieve a maximum output voltage accuracy of 3% while

operating in power-save mode (PFM mode). For output voltages

≥ 2 V, an inductor of 10 µH and an output capacitor of ≥ 10 µF is

recommended. See the Application Information section for external components.
