INPUT CHARACTERISTICS
DYNAMIC RESPONSE
No load set point is 5 mV higher than the nominal voltage, to partially compensate voltage drop on the output pins.
Load regulation is affected with resistance of the output pins (approximately 0.3 mΩ) since there is no remote sense.
Cross regulation is affected with resistance of the RETURN pin (approximately 0.3 mΩ) since there is no remote sense.
