6.1 Absolute Maximum Ratings

Under the recommended operating junction temperature range of -40°C to 125°C (unless otherwise noted) (1)
MIN MAX UNIT
VIN to GND –0.2 6 V
EN, MODE, FB, PG, to GND(2) –0.2 VIN+0.2
VOUT to GND(2) –0.2 VIN+0.2
Junction temperature 150 °C
Peak soldering reflow temperature for Pb(3) 240 °C
Peak soldering reflow temperature for No-Pb(3) 260
Storage temperature range –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) The absolute maximum voltage on this pin must not exceed 6V with respect to ground. Do not allow the voltage on the output pin to exceed the voltage on the input pin by more than 0.2 V.
(3) For soldering information, refer to the following document: SNOA401.
