Note 3:

100% production test at +25°C. Specifications over the temperature range are guaranteed by design

and characterization.

Note 4:

See thermal regulation specifications for changes in output voltage due to heating effects. Load line

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

Note 5:

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.

Note 6:

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