LM809M3X-2.93 from Texas Instruments, in a SOT-23-3. 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 | GND | power_in | Ground reference connection. |
| 2 | RESET | output | Active-low reset output; asserted low when VCC falls below the 2.93 V reset threshold and remains asserted for 240 ms after VCC rises above threshold. |
| 3 | VCC | power_in | Supply voltage input, 1.2 to 5.5 V operating range over -40°C to 105°C. |
