6 Specifications
6.1 Absolute Maximum Ratings
see (1)(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
6.2 ESD Ratings

|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human-body model (HBM), per AEC Q100-002(1) | ±2000 | V |
| Charged-device model (CDM), per AEC Q100-011 | ±500 | |||
(1) AEC Q100-002 indicates that HBM stressing shall be in accordance with the ANSI/ESDA/JEDEC JS-001 specification.

(1) Minimum VIN = VOUT + VDO or 1.7 V, whichever is greater.
(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.
6.6 Typical Characteristics
For all voltage versions, at TJ = 25°C, VIN = VOUT(nom) + 0.5 V, IOUT = 10 mA, VEN = 1.7 V, and COUT = 0.1 μF, unless otherwise noted.
