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.

Note 3: The LT3060 is tested and specified under pulse load conditions

Performance at –40°C to 125°C is assured by design, characterization

and correlation with statistical process controls. The LT3060I regulator is

guaranteed over the full –40°C to 125°C operating junction temperature

range. The LT3060MP is 100% tested over the –55°C to 125°C operating

junction temperature range. The LT3060H is 100% tested over the

–40°C to 150°C operating junction temperature range. High junction

temperatures degrade operating lifetimes. Operating lifetime is derated at

junction temperatures greater than 125°C.

Note 4: The LT3060 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

Note 6: To satisfy minimum input voltage requirements, the LT3060 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. The 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

voltages, minimum input voltage requirements limit dropout voltage.

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

Note 13: This IC includes overtemperature protection that protects the

device during momentary overload conditions. Junction temperature

will exceed 125°C (LT3060E, LT3060I, LT3060MP) or 150°C (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.
