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 LT3009 regulators are tested and specified under pulse load
conditions such that T
J
≈ T
A
. The LT3009E is 100% tested at T
A
= 25°C.
Performance at –40°C and 125°C is assured by design, characterization
and correlation with statistical process controls. The LT3009I is guaranteed
over the full –40°C to 125°C operating junction temperature range.
Note 4:
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 the
maximum input voltage, the output current range must be limited. When
operating at the maximum output current, the input voltage must be limited.
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 equals (V
IN
– V
DROPOUT
). For the LT3009-1.2, dropout
voltage will be limited by the minimum input voltage under some voltage/
load conditions.
Note 6:
To satisfy minimum input voltage requirements, the LT3009
adjustable version is tested and specified for these conditions with an
external resistor divider (61.9k bottom, 280k top) which sets V
OUT
to 3.3V.
The external resistor divider adds 9.69μA of DC load on the output. This
external current is not factored into GND pin current.
Note 7:
GND pin current is tested with V
IN
= V
OUT(NOMINAL)
+ 0.5V and a
current source load. GND pin current will increase in dropout. For the fixed
output voltage versions, an internal resistor divider will add to the GND
pin current (∼2μA for the LT3009-5,
∼1μA
for the LT3009-1.2, LT3009-1.5,
LT3009-1.8, LT3009-2.5 and LT3009-3.3). See the GND Pin Current curves
in the Typical Performance Characteristics section.
Note 8:
The
SHDN
pin can be driven below GND only when tied to the IN
pin directly or through a pull-up resistor. If the
SHDN
pin is driven below
GND by more than –0.3V while IN is powered, the output will turn on.
Note 9:
Output noise is listed for the adjustable version with the ADJ pin
connected to the OUT pin. See the RMS Output Noise vs Load Current
curve in the Typical Performance Characteristics Section.
