For output voltages
≤ 1.2 V, a 22
F 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
H and an output capacitor of ≥ 10 F is
recommended. See the Application Information section for external components.
