NOTE:
1. Output noise and ripple measured with 47µF electrolytic & 0.1µF ceramic capacitors across output.
2. Voltage accuracy is set at 60% rated load & 25°C ambient temperature.
3. Line regulation is measured from High Line to Low Line at rated load.
4. Load regulation is measured from 20% -100% of full load.
