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