4.
Specifications apply at the input voltage from 8V to 14V, output load from 0 to 5A, ambient temperature from 0°C
to 70°C, output capacitance consisting of 3x22µF ceramics and a 47µF tantalum, and the CCA=0 unless otherwise
noted.

Therefore maximum allowable negative current under specific conditions is 20% lower than the current determined from the derating curves
shown in paragraph 5.5

Digital PWM has an inherent quantization uncertainty of ±6.25mV that is not included in the specified static regulation parameters.
At the negative output current (bus terminator mode) efficiency of the ZY2105 degrades resulting in increased internal power dissipation.
