(2) 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. (3) TPS73601 is tested at VOUT = 2.5 V. (4) Tolerance of external resistors not included in this specification. (5) VDO is not measured for fixed output versions with VOUT(nom) < 1.8 V. (6) Fixed-voltage versions only; see Application and Implementation for more information. 6.5 Electrical Characteristics Over operating temperature range (TA = –40°C to 125°C), VIN = VOUT(nom) + 0.5 V (1), I OUT = 10 mA, VEN = 1.7 V, and COUT = 0.1 μF, unless otherwise noted. Typical values are at TJ = 25°C.
