This is the worst-case GND pin current. GND pin current decreases slightly  
at higher input voltages.

Note 3. Maximum junction temperature limits operating conditions. The  
regulated output voltage specification does not apply for all possible  
combinations of input voltage and output current. If operating at maximum  
output current, limit the input voltage range. If operating at maximum  
input voltage, limit the output current range.  
Note 4. To satisfy minimum input voltage requirements, the LT3015 is  
tested and specified for these conditions with an external resistor divider  
(54.9k top, 49.9k bottom) for an output voltage of –2.56V. The external  
resistor adds 25μA of DC load on the output.

specifications from 0°C to 125°C junction temperature. Specifications over  
the –40°C to 125°C operating temperature range are assured by design,  
characterization, and correlation with statistical process controls. The  
LT3015I is guaranteed over the full –40°C to 125°C operating junction  
temperature range. The LT3015MP is 100% tested and guaranteed over  
the full –55°C to 125°C operating junction temperature range.  
Note 10. Parasitic diodes exist internally between the OUT, ADJ, SHDN pins  
and the IN pin. Do not drive the OUT, ADJ, and SHDN pins more that 0.3V  
below the IN pin during fault conditions, and these pins must remain at a  
voltage more positive than IN during normal operation.
