*Notice: *Stresses above 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
above those indicated in the operation sections of the
specifications is not implied. Exposure to Absolute
Maximum Rating conditions for extended periods may
affect device reliability.

Note 1: Limits are 100% production tested at T
A = +25°C. Limits over the operating temperature range are ensured through cor-
relation using Statistical Quality Control (SQC) methods.
2: Validated by line regulation test.
3: Not tested. For design purposes, the current limit should be considered 150 mA minimum to 410 mA maximum.
4: The dropout voltage is defined as (V
IN – VOUT) when VOUT is 100 mV below the value of VOUT for
V
IN = VOUT +2V.
