4.
Specifications apply at the input voltage from 8V to 14V, output load from 0 to 20A, ambient temperature from 0°C
to 70°C, output capacitance consisting of 110μF ceramic and 220μF tantalum, and the CCA=1 unless otherwise
noted.

ZD-02139 Rev. 1.0 04NOV08
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 ZY2120 degrades resulting in increased internal power dissipation.
