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: Absolute maximum input-to-output differential voltage is not
achievable with all combinations of rated IN pin and OUT pin voltages.
With the IN pin at 50V, the OUT pin may not be pulled below 0V. The total
measured voltage from IN to OUT must not exceed ±50V. If OUT is above
ground, do not actively pull OUT above IN by more than 40V.
Note 3: The LT3060 regulators are tested and specified under pulse load
conditions such that T
J
≅ T
A
. The LT3060E regulators are 100% tested
at T
A
= 25°C. Performance at –40°C to 125°C is assured by design,
characterization and correlation with statistical process controls. The
LT3060I regulators are guaranteed over the full –40°C to 125°C operating
junction temperature range. The LT3060MP regulators are 100% tested
over the –55°C to 150°C operating junction temperature range. The
LT3060H regulators are 100% tested at the 150°C operating junction
temperature. High junction temperatures degrade operating lifetimes.
Operating lifetime is derated at junction temperatures greater than 125°C.
Note 4: The LT3060 adjustable version is tested and specified for these
conditions with the ADJ connected to the OUT pin.
Note 5: Maximum junction temperature limits operating conditions. The
regulated output voltage specification does not apply for all possible
combinations of input voltage and output current. Limit the output current
range if operating at the maximum input-to-output voltage differential.
Limit the input-to-output voltage differential if operating at maximum
output current. Current limit foldback will limit the maximum output
current as a function of input-to-output voltage. See Current Limit vs

in the Typical Performance Characteristics section.
Note 6: To satisfy minimum input voltage requirements, the LT3060
adjustable version is tested and specified for these conditions with an
external resistor divider (bottom 115k, top 365k) for an output voltage of
2.5V. The external resistor divider adds 5µA of DC load on the output. This
external current is not factored into GND pin current.
Note 7: Dropout voltage is the minimum input-to-output voltage
differential needed to maintain regulation at a specified output current.
In dropout, the output voltage equals: (V
IN
– V
DROPOUT
). For the
LT3060, LT3060-1.2, LT3060-1.5 and LT3060-1.8, dropout is limited
by the minimum input specification under some output voltages and
load conditions. See the Minimum Input Voltage curve in the Typical
Performance Characteristics section.
Note 8: GND pin current is tested with V
IN
= V
OUT(NOMINAL)
+ 0.55V and a
current source load. GND pin current will increase in dropout. See GND pin
current curves in the Typical Performance Characteristics section.
Note 9: ADJ pin bias current flows out of the ADJ pin.
Note 10: SHDN pin current flows into the SHDN pin.
Note 11: Reverse output current is tested with the IN pin grounded and the
OUT pin forced to the rated output voltage. This current flows into the OUT
pin and out of the GND pin.
Note 12: To satisfy requirements for minimum input voltage, current
limit is tested at V
IN
= V
OUT(NOMINAL)
+ 1V or V
IN
= 2.1V, whichever is
greater.
Note 13: This IC includes overtemperature protection that protects the
device during momentary overload conditions. Junction temperature
will exceed 125°C (LT3060E, LT3060I) or 150°C (LT3060MP, LT3060H)
when overtemperature circuitry is active. Continuous operation above the
specified maximum junction temperature may impair device reliability.
Note 14: The dropout voltage specification is guaranteed for the DFN
package. The dropout voltage specification for high output currents cannot
be guaranteed for the TS8 package due to production test limitations.
Note 15: The load regulation specification is guaranteed for the fixed
voltage options in the DFN package. The load regulation specification
cannot be guaranteed for the fixed voltage options in the TS8 package due
to production test limitations. The TS8 packages are tested similarly to the
LT3060 adjustable version with the ADJ connected to the OUT pin.
