4. Voltage range specified in the Output Stage of the Electrical Characteristics in boldface type.

5. For VIN ≤ 4.5 V, a RESET = Low may occur with the output in regulation.

6. Part is guaranteed by design to meet specification over the entire VIN voltage range, but is production tested only at the specified VIN voltage.

7. Minimum VIN = 4.5 V for 2.5 V, 3.3 V, and Adjustable options. Minimum VIN = 6.0 V for 5.0 V option.
