(1) Minimum VIN = VOUT + VDO or 2.2 V, whichever is greater.
(2) For VOUT(nom) < 1.6 V, when VIN ≤ 1.6 V, the output locks to VIN and may result in an overvoltage condition on the output. To avoid this situation, disable the device before powering down VIN.
(3) TPS73701 is tested at VOUT = 1.2 V.
(4) Tolerance of external resistors not included in this specification.
(5) VDO is not measured for fixed output versions with VOUT(nom) < 2.3 V, because minimum VIN = 2.2 V.
(6) Fixed-voltage versions only; see the Reverse Current section for more information.
