LT3009 Series
PIN FUNCTIONS
(SC70/DFN)
SHDN (Pin 1/Pin 5): Shutdown. Pulling the SHDN pin
low puts the LT3009 into a low power state and turns the
output off. If unused, tie the SHDN pin to V IN . The LT3009
does not function if the SHDN pin is not connected. The
SHDN pin cannot be driven below GND unless tied to the
IN pin. If the SHDN pin is driven below GND while IN is
powered, the output will turn on. SHDN pin logic cannot
be referenced to a negative rail.
GND (Pins 2, 3, 4/Pin 6): Ground. Connect the bottom
of the resistor divider that sets output voltage directly to
GND for the best regulation.
IN (Pin 5/Pin 4): Input. The IN pin supplies power to the
device. The LT3009 requires a bypass capacitor at IN if
the device is more than six inches away from the main
input ?lter capacitor. In general, the output impedance
of a battery rises with frequency, so it is advisable to
include a bypass capacitor in battery-powered circuits. A
bypass capacitor in the range of 0.1μF to 10μF will suf-
?ce. The LT3009 withstands reverse voltages on the IN
pin with respect to ground and the OUT pin. In the case
of a reversed input, which occurs with a battery plugged
in backwards, the LT3009 acts as if a large resistor is in
series with its input. Limited reverse current ?ows into
the LT3009 and no reverse voltage appears at the load.
OUT (Pin 6/Pins 2, 3): Output. This pin supplies power to
the load. Use a minimum output capacitor of 1μF to prevent
oscillations. Large load transient applications require larger
output capacitors to limit peak voltage transients. See the
Applications Information section for more information on
output capacitance and reverse output characteristics.
ADJ (Pin 7/Pin 1): Adjust. This pin is the error ampli?er’s
inverting terminal. Its 300pA typical input bias current
?ows out of the pin (see curve of ADJ Pin Bias Current vs
Temperature in the Typical Performance Characteristics
section). The ADJ pin voltage is 600mV referenced to GND
and the output voltage range is 600mV to 19.5V. This pin
is not connected in the ?xed output voltage versions.
NC (Pins 7, 8/Pin 1): No Connect. For the adjustable voltage
version, Pin 8 is an NC pin in the SC70 package. For the
?xed voltage versions, Pin 7 and Pin 8 are NC pins in the
SC70 package, and Pin 1 is an NC pin in the DFN package.
NC pins are not tied to any internal circuitry. They may be
?oated, tied to V IN or tied to GND.
Exposed Pad (Pin 7, DFN Package Only): Ground. The
Exposed Pad (backside) of the DFN package is an electri-
cal connection to GND. To ensure optimum performance,
solder Pin 7 to the PCB and tie directly to Pin 6.
The device protects both itself and the load.
