NOTE: Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress
ratings only, and function operation of the device at these or any other conditions beyond those indicated under “recommended operating
conditions” is not implied. Exposure to absolute‐maximum–rated conditions for extended periods may affect device reliability.

NOTES：
1. Measured using a double sided board with 1”x 2” square inches of copper area connected to the GND pins for “heat spreading”.
2. EN pin input voltage must be always less than or equal to input voltage.
