(2) For VOUT(nom) <1.6V, when VIN≤ 1.6V, the output will lock 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. (3) VDO is not measured for the TPS73615 (VOUT(nom) = 1.5V) since minimum VIN = 1.7V. (4) Refer to Applications section for more information. 3 |
