(1) The minimum input voltage is the lowest ensured voltage that will produce the nominal output voltage. See the Drop-Out Voltage section for information on drop-out voltage.
(2) Specified by design. Not production tested.
(3) See the efficiency graphs in the Typical Characteristics section for efficiency over the entire load range.
(4) The maximum output capacitance of 500 μF includes the combination of both ceramic and non-ceramic capacitors.
