7.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted) (1)(2)| MIN | MAX | UNIT | |||
|---|---|---|---|---|---|
| Voltage range on IN, OUT, EN or EN, ILIM, FAULT | –0.3 | 7 | V | ||
| Voltage range from IN to OUT | –7 | 7 | V | ||

(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.
(2) Voltages are referenced to GND unless otherwise noted.
7.2 ESD Ratings
| VALUE | UNIT | ||||
|---|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) | ±2000 | V | |

| IEC 61000-4-2 contact discharge(3) | ±8000 | ||||
| IEC 61000-4-2 air-gap discharge(3) | ±15000 | ||||
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
(3) Surges per EN61000-4-2. 1999 applied to output terminals of EVM. These are passing test levels, not failure threshold.
