When measuring output ripple, it is recommended that an external 0.47 µF ceramic capacitor be placed from the +Vout pin to the -Vout pin for single output units and from each output to common for dual output units. For noise sensitive applications, the use of 3.3 µF capacitors will reduce the output ripple. 2. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%. 3. No-load operation will not damage these units, however, they may not meet specifications. 4. Dual output units may provide a 10V, 24V or 30V output. To do this, connect the load across the positive (+Vout) and negative (-Vout) outputs and float the output common. 5. The converter should be connected to a low ac-impedance source. An input source with a highly inductive impedance may affect the stability of the converter. In applications where the converter output loading is high and input power is supplied over long lines, it may be necessary to use a capacitor on the input to insure start-up. In this case, it is recommended that a low ESR (ESR
