NOTES:
1
The power dissipation values are based on the condition that junction temperature T
J
and ambient temperature T
A
difference is
100°C.
2
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.
3
The power dissipation of VSON‐6 (2x2) would be 500mW normally with the 0.5X0.5 square inches cooper area connected to the
bottom pad. However, it could be up to 1000mW with larger cooper area.

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.
3
EN Pin with internal pull high resistor is about several hundreds of KΩ for RS7212 only.
