7 Specifications
7.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)(2)(3)| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| Voltage range on IN, OUT, EN, FLT (3) | –0.3 | 6 | V | |
| Voltage range from IN to OUT | –6 | 6 | V | |
| Maximum junction temperature, TJ | Internally Limited | |||
| Storage temperature, Tstg | –60 | 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) Absolute maximum ratings apply over recommended junction temperature range.
(3) Voltages are with respect to GND unless otherwise noted.
(4) VOUT was surged on a pcb with input and output bypassing per Input and Output Capacitance (except input capacitor was 22 µF) with no device failures.
