PIN FUNCTIONS (DD/ST/TS8)
IN (Pins 7, 8/Pin 3/Pins 7, 8): Input. This pin supplies
power to bias internal circuitry and supply output load
current. For the device to operate properly and regulate,
the voltage on this pin must be 1.2V to 1.4V above the
OUT pin (depending on output load current—see the
dropout voltage specications in the Electrical Charac-
teristics table).
NC (Pins 3, 5, 6/NA/Pins 1, 6): No Connection. These
pins have no connection to internal circuitry and may be
tied to IN, OUT, GND or oated.
OUT (Pins 1, 2/Pin 2/Pins 2, 3, 4): Output. This is the
power output of the device. The minimum current source
value to which the LT3092 can be set is 0.5mA or the
device will not regulate.
SET (Pin 4/Pin 1/Pin 5): Set. This pin is the error ampli-
er’s noninverting input and also sets the operating bias
point of the circuit. A xed 10μA current source ows out
of this pin. Two resistors program IOUT as a function of
the resistor ratio relative to 10μA. Output current range
is 0.5mA to the maximum rated 200mA level.
Exposed Pad/Tab (Pin 9/Tab/NA): Output. The Exposed
Pad of the DFN package and the Tab of the SOT-223
package are tied internally to OUT. Tie them directly to
the OUT pins (Pins 1, 2/Pin 2) at the PCB. The amount
of copper area and planes connected to OUT determine
the effective thermal resistance of the packages (see the
Applications Information section).
