LM2705MFX-ADJ from Texas Instruments, in a SOT-23-5. 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 | SW | input | Power switch input, the drain of the internal NMOS power switch, with an absolute maximum SW voltage of 21 V; minimize the metal trace area connected to this pin to reduce EMI. |
| 2 | GND | power_in | Ground, to be tied directly to the ground plane. |
| 3 | FB | input | Output voltage feedback input, where R1 = R2 × (VOUT / 1.237 V) - 1 sets the output voltage, with an absolute maximum FB voltage of 2 V. |
| 4 | SHDN | input | Active-low shutdown pin: drive above 1.1 V to enable the device and below 0.3 V to place it in low-power shutdown, with an absolute maximum SHDN voltage of 7.5 V. |
| 5 | VIN | power_in | Analog and power input supply pin, operating over 2.2 V to 7 V. |
