Note 1: Stresses beyond those listed under Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to any Absolute  
Maximum Rating condition for extended periods may affect device  
reliability and lifetime.  
Note 2: The LT3015 adjustable version is tested and specified for these  
conditions with the ADJ pin connected to the OUT pin.  
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, especially due to the  
current limit foldback which starts to decrease current limit at about  
Note 8: Positive SHDN pin current flows into the SHDN pin.  
Note 9: The LT3015 is tested and specified under pulsed load conditions  
such that T ≅ T . The LT3015E is guaranteed to meet performance  
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.

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.  
Note 5: Dropout voltage is the minimum input-to-output voltage  
differential needed to maintain regulation at a specified output current. In  
Note 11: The SHDN threshold must be met to ensure device operation.  
Note 12: For LT3015, the minimum input voltage refers to the lowest  
input voltage before the parts goes out of regulation. For the fixed voltage  
versions of LT3015, the minimum input voltage refers to the lowest input  
voltage before the part can no longer sink 1.5A; for proper regulation, the  
dropout voltage requirements must be met.  
Note 13: Sense pin current flows out of the pin.  
Note 14: The current limit circuit incorporates foldback that decreases  
dropout, the output voltage is: V + V

Note 6: GND pin current is tested with V = V

This is the worst-case GND pin current. GND pin current decreases slightly
