Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

Note 1:
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-
layer board. For detailed information on package thermal considerations, refer to

Note 2:
All devices are 100% production tested at T
A
= +25NC. Limits over the operating temperature range are guaranteed by
design and not production tested.
Note 3:
Thermally limited, guaranteed by design, and not production tested.
Note 4:
In linear mode, as I
OUT
increases, the OUT voltage drops due to a voltage across Q1 (see
Functional Diagram).
Note 5:
All timing characteristics are measured using 20% and 80% levels unless otherwise specified.
