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
|V IN ?– V OUT | = 8V. 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.
Note 5: Dropout voltage is the minimum input-to-output voltage
differential needed to maintain regulation at a specified output current. In
dropout, the output voltage is: V IN + V DROPOUT .
Note 6: GND pin current is tested with V IN = V OUT(NOMINAL) and a current
source load. Therefore, the device is tested while operating in dropout.
This is the worst-case GND pin current. GND pin current decreases slightly
at higher input voltages.
Note 7: Positive ADJ pin bias current flows into the ADJ pin.
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 J ? T A . 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.
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
current limit for |V IN – V OUT | ≥ 8V. Some level of output current is
provided at all V IN – V OUT differential voltages. Please consult the Typical
Performance Characteristics graph for Current Limit vs V IN – V OUT .
