Note:
1. Ripple and noise are measured at full load, 20 MHz BW with 10μF tantalum capacitor and 1μF ceramic capacitor across the output. The 48 Vdc output models require a
22uF aluminum capacitor and a 1uF ceramic capacitor across the output.
2. An external input capacitor of 470uF is recommended to reduce input ripple voltage.
