Notes: 1. See thermal regulation specification for changes in output voltage due to heating effects. Load regulation and line regulation
are measured with low duty cycle pulse testing to maintain a constant junction temperature.
2. Dropout voltage is specified over the full output current range. Dropout voltage is defined as the minimum input/output
differential measured at the specified output current.
3. Minimum load current is defined as the minimum output current required to maintain regulation.
