(1) Minimum V_IN = V_OUT + V_DO 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) V_DO is not measured for output versions with V_OUT(nom) < 1.8V, because minimum V_IN = 1.7V.

(5) Fixed-voltage versions only; refer to Application Information section for more information.
