ELECTRICAL CHARACTERISTICS (continued)
CURRENT REGULATION LOOP
Note 1: A load step of 2 A can be applied provited that input-output differential voltage is lower than 20 V (see Figure 3).
Note 2: The same performance can be maintained at higher output levels if a bypassing capacitor is provited between pins 2 and 4.
