*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 operational sections of the specifications

is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.

1. Tested to EIA/JESD22–A114–A

2. Tested to EIA/JESD78

3. Limits are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed through correlation using

Statistical Quality Control (SQC) Methods.

4. Guaranteed by line regulation test.

5. Not tested. For design purposes, the current limit should be considered 150 mA minimum to 410 mA maximum.

6. The dropout voltage is defined as (VIN – VOUT) when VOUT is 100 mV below the value of VOUT for VIN = VOUT + 2.0 V.
