(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) If used in a dual-supply system where the regulator load is returned to a negative supply, the output pin must be diode clamped to
ground.
(3) At elevated temperatures, device power dissipation must be derated based on package thermal resistance and heatsink values (if a
heatsink is used). When using the WSON package, refer to TI Application Report AN-1187 Leadless Leadframe Package (LLP)
(SNOA401) and the WSON Mounting section in this datasheet. If power dissipation causes the junction temperature to exceed specified
limits, the device goes into thermal shutdown.
6.2 ESD Ratings
V(ESD) Electrostatic discharge
Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1)
VALUE
±2000
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
