Additional Notes:
2. No load set point is 5 mV higher than the nominal voltage, to partially compensate voltage drop on the output pins.
3. Load regulation is affected with resistance of the output pins (approximately 0.3 m ? ) since there is no remote sense.
4. Cross regulation is affected with resistance of the RETURN pin (approximately 0.3 m ? ) since there is no remote sense.
