The output range (50% load) is limited by Vin. See detailed specs for full conditions. Use adequate ground plane and copper thickness adjacent to the converter. All specifications are a t nominal line voltage, Vout=nominal (3.3V for W5 models) and full load, +25 deg.C. unless otherwise noted. Ripple and Noise (R/N) are shown at Vout=1V. See specs for details. Output capacitors are 10 F ceramic. Input cap is 22 F. See detailed specifications. No load input current is shown at Vout = 3.3V.
