(1) Minimum VIN = VOUT + VDO or 1.7V, whichever is greater.
(2) TPS73201 is tested at VOUT = 2.5V.
(3) Tolerance of external resistors not included in this specification.
(4) VDO is not measured for output versions with VOUT(nom) < 1.8V, because minimum VIN = 1.7V.
(5) Fixed-voltage versions only; refer to Application Information section for more information.
