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 section s of the sp ecifica tions is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.

NOTE 1: Line regulation and load regulation are inherently tested by input voltage and load current performed
under the conditions and limits of the output voltage tests.
NOTE 2: The standby current typically settles to 25µA, (-55°C to +125°C), within 2 seconds; however to decrease
test time, part is guaranteed at 100µA maxi mum val ue.
