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 LT3013 is tested and speciﬁed for these conditions with the

ADJ pin connected to the OUT pin.

Note 3: Operating conditions are limited by maximum junction

temperature. The regulated output voltage speciﬁcation will not apply

for all possible combinations of input voltage and output current. When

operating at maximum input voltage, the output current range must be

limited. When operating at maximum output current, the input voltage

range must be limited.

Note 4: To satisfy requirements for minimum input voltage, the LT3013 is

tested and speciﬁed for these conditions with an external resistor divider

(249k bottom, 649k top) for an output voltage of 4.5V. The external

resistor divider will add a 5μA 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 will be equal to (VIN – VDROPOUT).

Note 6: GND pin current is tested with VIN = 4.75V and a current source

load. This means the device is tested while operating close to its dropout

region. This is the worst-case GND pin current. The GND pin current will

decrease slightly at higher input voltages.

Note 7: ADJ pin bias current ﬂows into the ADJ pin.

Note 8:

SHDN pin current ﬂows out of the SHDN pin.

Note 9: 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 the GND pin.

Note 10: The LT3013E is guaranteed to meet performance speciﬁcations

from 0°C to 125°C operating junction temperature. Speciﬁcations over

the –40°C to 125°C operating junction temperature range are assured by

design, characterization and correlation with statistical process controls.

The LT3013H is tested to the LT3013H Electrical Characteristics table at

140°C operating junction temperature. High junction temperatures degrade

operating lifetimes. Operating lifetime is derated at junction temperatures

greater than 125°C. The LT3013MP is 100% tested and guaranteed over

the –55°C to 125°C operating junction temperature range.

Note 11: This IC includes overtemperature protection that is intended

to protect the device during momentary overload conditions. Junction

temperature will exceed 125°C (LT3013E, LT3013MP) or 140°C (LT3013H)

when overtemperature protection is active. Continuous operation above

the speciﬁed maximum operating junction temperature may impair device

reliability.

ELECTRICAL CHARACTERISTICS

The

l denotes the speciﬁcations which apply over the –40°C to 140°C operating temperature range, otherwise speciﬁcations are at TJ = 25°C.
