The output range is limited by Vin. See detailed specs. Use adequate ground plane and copper thickness adjacent to the converter. All specifica tions are at nominal line voltage, Vout=nominal (3.3V) and full load, +25 deg.C. unless otherwise noted. Ripple and Noise (R/N) and no-load input current are shown at Vout=1V. See specs for details. Output capacitors are 10 F ceramic. Input cap is 22 F. See detailed specifications.
