(2) TPS73101 is tested at VOUT = 2.5 V. (3) Tolerance of external resistors not included in this specification. (4) VDO is not measured for fixed output versions with VOUT(nom) < 1.8 V because minimum VIN = 1.7 V. (5) Fixed-voltage versions only; refer to Application Information for more information.
