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 IN at 50V, do not pull OUT below 0V. The total differential voltage
from IN to OUT must not exceed +50V, –40V. If OUT is pulled above IN
and GND, the OUT to IN differential voltage must not exceed 40V.
Note 3:
The LT3065 regulator is tested and specified under pulse
load conditions such that T
J
≅
T
A
. The LT3065E 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 LT3065I regulators are
guaranteed over the full –40°C to 125°C operating junction temperature
range. The LT3065MP regulators are 100% tested over the –55°C to
150°C operating junction temperature range. The LT3065H 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 LT3065 adjustable version is tested and specified for these
conditions with the ADJ pin connected to the OUT pin.
Note 5:
Maximum junction temperature limits operating conditions.
Regulated output voltage specifications do not apply for all possible
combinations of input voltage and output current. If operating at the
maximum input voltage, limit the output current range. If operating at
the maximum output current, limit the input voltage range. 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:
Dropout voltage is the minimum IN-to-OUT differential voltage
needed to maintain regulation at a specified output current. In dropout,
the output voltage equals (V
IN
– V
DROPOUT
). For some output voltages,
minimum input voltage requirements limit dropout voltage.
Note 7:
To satisfy minimum input voltage requirements, the LT3065 is
tested and specified for these conditions with an external resistor divider
(60.4k bottom, 442k top) which sets V
OUT
to 5V. The divider adds 10uA of
output DC load. This external current is not factored into GND pin current.
Note 8:
GND pin current is tested with V
IN
= V
OUT(NOMINAL)
+ 0.6V and a
current source load. GND pin current increases in dropout. See GND pin
current curves in the Typical Performance Characteristics section.
Note 9:
To satisfy requirements for minimum input voltage, current limit is
tested at V
IN
= V
OUT(NOMINAL)
+ 1V or V
IN
= 2.2V, whichever is greater.
Note 10:
ADJ pin bias current flows out of the ADJ pin.
Note 11:
SHDN
pin current flows into the
SHDN
pin.
Note 12:
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
pin and out of the GND pin.
Note 13:
Current limit varies inversely with the external resistor value tied
from the IMAX pin to GND. For detailed information on selecting the IMAX
resistor value, see the Operation section. If the externally programmed
current limit feature is unused, tie the IMAX pin to GND. The internal
current limit circuitry implements short-circuit protection as specified.
Note 14:
This IC includes over temperature protection that protects the
device during overload conditions. Junction temperature exceeds 125°C
(LT3065E, LT3065I) or 150°C (LT3065MP, LT3065H) when the over
temperature circuitry is active. Continuous operation above the specified
maximum junction temperature may impair device reliability.
