6 Specifications
6.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted) (1)| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| Voltage | Input voltage(2) | –0.3 | 6 | V |
| Maximum dc output voltage | 4.9 | V | ||
| Current | Peak output current | Internally limited | A | |

| Storage temperature, Tstg | –65 | 150 | °C | |
(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) All voltage values are with respect to network ground pin.
6.2 ESD Ratings
| VALUE | UNIT | |||
|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) | ±2000 | V |
| Charged-device model (CDM), per JEDEC specification JESD22-C101(2) | ±500 | |||
(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.

(1) Minimum VI = VO + V(DO) or the minimum value specified here, whichever is greater.
(2) Continuous output current is limited by internal protection circuitry, but it is not recommended that the device operate above this maximum for extended periods of time.
(3) Minimum VI is specified in (1).
(4) V(DO) is not measured for the TPS79718 because minimum VI > 1.7 V.
