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 pull IN more than 40V below OUT.
Note 3:
The LT3062 is tested and specified under pulse load conditions
such that T
J
≅
T
A
. The LT3062E regulators are 100% tested at T
A
= 25°C
and performance is guaranteed from 0°C to 125°C. Performance at
–40°C to 125°C is assured by design, characterization and correlation
with statistical process controls. The LT3062I regulators are guaranteed
over the full –40°C to 125°C operating junction temperature range. The
LT3062MP regulators are 100% tested over the –55°C to 150°C operating
junction temperature. The LT3062H regulators are 100% tested at the
150°C operating junction temperature. High junction temperatures degrade
operating lifetimes. Operating lifetime is derated at junction temperature
greater than 125°C.
Note 4:
The LT3062 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 voltage. Limit the input-to-output
voltage differential if operating at maximum output current. Current limit
foldback limits the maximum output current as a function of input-to-
output voltage. See Current Limit vs V
IN
– V
OUT
in the Typical Performance
Characteristics section.
Note 6:
To satisfy minimum input voltage requirements, the LT3062
adjustable version is tested and specified for these conditions with an
external resistor divider (bottom 60k, top 230k) for an output voltage of
2.9V. The external resistor divider adds 10µA 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
dropout, the output voltage equals: (V
IN
– V
DROPOUT
).
Note 8:
GND pin current is tested with V
IN
= V
OUT(NOMINAL)
+ 0.6V and a
current source load. GND pin current will increase in dropout. See GND
pin current curves in the Typical Performance Characteristics section. For
fixed voltage options, an internal resistor divider will add 5μA to the GND
pin current. See the 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:
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 12:
This IC includes thermal limit which protects the device during
momentary overload conditions. Junction temperature exceeds 125°C
(E-Grade and I-Grade) or 150°C (MP-Grade and H-Grade) when thermal
limit is active. Continuous operation above the specified maximum
junction temperature may impair device reliability.
Note 13:
Reverse output current is tested with the IN pin grounded and the
OUT pin forced to the specified voltage. This current flows into the OUT
