NOTES:
1. Measured with 1uF ceramic capacitor connect to output
pins.
2. Measured from high line to low line.
3. Measured from full load to 10% load.
4. This converter require a minimum 10% loading on their
output to maintain specified regulation. Operation under
no-load conditions will not damage these devices;
however they may not meet all listed specifications.
