ELECTRICAL CHARACTERISTICS The l denotes specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VOUT = 5V, VIN = 7V, IOUT = 0, VSHDN = 3V, ILIM2 and ILIM4 tied to VIN.
To avoid confusion with “min” and “max” as applied to negative voltages, all voltages are shown as absolute values except where
polarity is not obvious.
