LT3080IST#TRPBF from Analog Devices, in a SOT-223-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SET | input | A fixed 10µA current flows out of this pin through a single external resistor that programs the output voltage, and the SET pin voltage relative to OUT is limited to ±0.3V with current limited to ±10mA. |
| 2 | OUT | power_out | This is the power output of the device, and a minimum load current of 1mA is required or the output may not regulate. |
| 3 | IN | power_in | This pin is the collector of the power device and supplies the output load current; it must be more than 0.1V to 0.5V greater than the output voltage for regulation, and it is tied internally to VCONTROL on this package. |
