denotes specifi cations which apply over the full operating temperature range, otherwise specifi cations 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. PARAMETER CONDITIONS MIN TYP MAX UNITS
