Output Voltage.
No Int ernal Connection.
Ground. The exposed pad must be soldered to a large PCB and
connected to GND for maximum powe r dissipation.
Absolute Maximum Ratings
These are stress ratings only and functional operation is not implied. Exposure to absolute
maximum ratings for prolonged time periods may affect device reliability. All voltages are with
respect to ground.
