*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

IN = VOUT +2V.
