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.

) ........140°C/W
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:
Limits are 100% production tested at T
A
= +25°C. Limits over the operating temperature range are guaranteed through cor-
relation using Statistical Quality Control (SQC) methods.
Note 3:
Guaranteed by line-regulation test.
Note 4:
Adjustable mode only.
Note 5:
For design purposes, the current limit should be considered 120mA minimum to 420mA maximum.
