LM2931T-5.0 from Texas Instruments, in a TO-220. 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 | IN | power_in | Unregulated input voltage pin; operating range up to 26V, with overvoltage protection to 50V for LM2931-N and reverse-battery protection. |
| 2 | GND | power_in | Ground pin, which is also connected to the TO-220 tab; the regulator ground lead carries the quiescent current. |
| 3 | OUT | power_out | Regulated 5V output, with over 100 mA output current and a required output capacitor of at least 100 μF for stability. |
