The

l denotes the speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations are at TJ = 25°C.

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 LT3014 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 LT3014 is

tested and speciﬁed for these conditions with an external resistor divider

(249k bottom, 392k top) for an output voltage of 3.3V. The external

resistor divider adds 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 is equal to (VIN – VDROPOUT).

Note 6: GND pin current is tested with VIN = VOUT (nominal) and a current

source load. This means the device is tested while operating in its dropout

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

decreases 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 of the GND pin.

Note 10: The LT3014 is tested and speciﬁed under pulse load conditions

such that TJ ≅ TA. The LT3014E is 100% tested at TA = 25°C. Performance

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