NOTES
1. Dual output models require a minimum loading on the output to maintain specified regulations. Operation under no-load conditions will not
damage these devices; however, they may not meet all listed specifications.
2. Ripple & Noise is measured 20MHz limited bandwidth and with 0.1µF and 47µF capacitors in parallel across the output.
