Start up time is measured at nominal input and with a constant resistive load. 2. Load regulation is specified for a load change of minimum load to full load. 3. When measuring output ripple, it is recommended that an external 1 µF capacitor and 10 µF capacitor be connected in parallel from the +VOUT to the -VOUT pins. 4. Transient recovery is measured to within a 1% error band for a load step change of 25%. 5. Short circuit protection is provided by a “hiccup mode” circuit. 6. Operation at no-load will not damage the unit. 7. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selec- tion table above for the correct rating. An external resister may be added to adjust the converter output. To adjust the output UP, connect a 5%, 3W resistor between the minus output pin (5) and the Vout trim pin (6). To adjust the output DOWN, connect a 5%, 3W resistor between the plus output pin (4) and the Vout trim pin (6). The trim table at right gives suggested resistor values for this adjustment.
