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. |
