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