(1) Minimum VIN = VOUT + VDO or 1.7V, whichever is greater.
(2) For VOUT(nom) < 1.6V, when VIN ≤ 1.6V, the output locks to VIN and may result in a damaging over-voltage condition on the output. To avoid this situation, disable the device before powering down VIN. (Legacy silicon only)
(3) TPS73601 is tested at VOUT = 2.5V.
(4) Tolerance of external resistors not included in this specification.
(5) VDO is not measured for output versions with VOUT(nom) < 1.8V, because minimum VIN = 1.7V.
(6) Fixed-voltage versions only; refer to Application Information section for more information.
