(1) Minimum VIN = VOUT + VDO or 1.7 V, whichever is greater.
(2) VDO is not measured for the TPS73615 (VOUT(nom) = 1.5 V) since minimum VIN = 1.7 V.
(3) See the Application and Implementation section for more information.
(4) For VOUT(nom) < 1.6 V, when VIN ≤ 1.6 V, the output locks to VIN and may result in a damaging over-voltage level on the output. To avoid this situation, disable the device before powering down the VIN.
