Texas Instruments · Supervisor And Reset ICs · SOT-23
LM809M3X-4.38 from Texas Instruments, in a SOT-23. 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 for the device. |
| 2 | RESET | output | Active-low reset output that remains low while VCC is below the reset threshold and for 240 ms after VCC rises above the reset threshold. |
| 3 | VCC | power_in | Supply voltage input, with a recommended range of 1.2 V to 5.5 V over −40°C to 105°C and an absolute maximum of 6 V. |
