NOTES: 1. Specifications apply over the full operating temperature range.

2. See thermal regulation specification for changes in output voltage due to heating effects. Load regulation and line regulation are

measured at a constant junction temperature by low duty cycle pulse testing.

3. Dropout voltage is specified over the full output current range of the device. Dropout voltage is defined as the minimum input/output

differential measured at the specified output current. Test points and limits are also shown on the Dropout Voltage curve.

4. Minimum load current is defined as the minimum output current required to maintain regulation.

*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.
