¹For input and output current speciﬁcations, negative current is deﬁned as coming out of (sourcing) the speciﬁed device pin.

²Typical data are for initial design estimations only, and assume optimum manufacturing and application conditions. Performance may vary for individual units, within the

speciﬁed maximum and minimum limits.

³V_ERR= [(V_REF/8) – V_SENSE] / (V_REF/8).

⁴Overcurrent protection (OCP) is tested at T_A= 25°C in a restricted range and guaranteed by characterization.
