Notes

1. The triple output required a minimum 20% loading on the output to maintain specified regulation. Operation under no-load condition will not damage these devices; however they may not meet all listed specification.

2. Load regulation for triple output:

Main output (V1): 20% to 100% with 20% to 100% balanced on auxiliaries. Auxiliary outputs (V2 and V3): 20% to 100% balanced on all outputs.

3. Cross regulation for triple output: Main output 100% load, auxiliary 100%, other auxiliary 25% to 100%. Auxiliary outputs (V2 and V3): Main output 100% load, auxiliary 100%, other auxiliary 25% to 100% or main output 25%, auxiliary 25%, other

auxiliary 25% to 100%.

All specifications are typical at nominal input, full load, and 25°C unless otherwise noted
