1. Measured from high line to low line at rated load.
2. Measured from full load to 10% load at 115 V ac.
3. Ripple & noise are measured at 20MHz bandwidth with 0.1 µf ceramic & 10 µf electrolytic capacitors on the output.
The two earth ground pads are connected to input earth ground.
4. See derating curves

parameter
conditions/description
output overload
current limiting starts at 105% of the rated output current and recovers automatically
output over voltage output voltage is limited by TVS clamping to: 6.8 V for 3.3 & 5 V models, 135% for all other models
output short circuit protected, long-term short circuit may reduce reliability
