Load regulation is measured for an output change of 20% to 100%. 2. When measuring output ripple, it is recommended that an external 0.33 μF ceramic capacitor be placed from each output to common. For noise sensitive applications, the use of 0.47 μF capacitors will reduce the output ripple. 3. Operation at no-load will not damage these units. However, they may not meet all specifications. 4. 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
