1 _{At the negative output current (bus terminator mode) efficiency of the ZY1015 degrades resulting in increased internal power dissipation.}
Therefore maximum allowable negative current under specific conditions is 20% lower than the current determined from the derating curves
shown in paragraph 5.5.
2 _{ZY1015 is a step-down converter, thus the output voltage is always lower than the input voltage as show in Figure 1.}
3 _{Digital PWM has an inherent quantization uncertainty of ±6.25mV that is not included in the specified static regulation parameters.}
