(1) The minimum VIN operating voltage is 2.7 V or VOUT(typ) + 1 V, whichever is greater. The maximum VIN voltage is 5.5 V. The maximum output current is 100 mA.
(2) If VOUT ≤ 1.8 V then VINmin = 2.7 V and VINmax = 5.5 V.
(3) Equals VIN voltage – VOUT(typ) – 100 mV; the TPS79118 dropout voltage is limited by the minimum input voltage range limitations.
