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 Selection table above for the correct rating. External Trim 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.
