Over Temperature Point
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.
