LM2931AM-5.0 from Texas Instruments, in a SOIC-8. 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 | OUT | power_out | Regulated 5 V output; sources up to 100 mA with dropout voltage ≤ 0.6 V at 100 mA and output tolerance ±3.8% (A grade) over 6 V ≤ VIN ≤ 26 V and −40 °C to +125 °C. |
| 2 | GND | power_in | Ground return; one of four internally connected ground pins; carries quiescent current ≤ 1.0 mA (IO ≤ 10 mA) plus load current. |
| 3 | GND | power_in | Ground return; one of four internally connected ground pins; carries quiescent current ≤ 1.0 mA (IO ≤ 10 mA) plus load current. |
| 4 | NC | unconnected | Not internally connected; leave unconnected (must be electrically isolated from the rest of the circuit in the DSBGA package variant; no special treatment needed for SOIC-8). |
| 5 | NC | unconnected | Not internally connected; leave unconnected (must be electrically isolated from the rest of the circuit in the DSBGA package variant; no special treatment needed for SOIC-8). |
| 6 | GND | power_in | Ground return; one of four internally connected ground pins; carries quiescent current ≤ 1.0 mA (IO ≤ 10 mA) plus load current. |
| 7 | GND | power_in | Ground return; one of four internally connected ground pins; carries quiescent current ≤ 1.0 mA (IO ≤ 10 mA) plus load current. |
| 8 | IN | power_in | Unregulated DC input; operating range 6 V to 26 V (fixed 5 V version); withstands load-dump transients up to 60 V (T = 1 ms, τ ≤ 100 ms) and reverse-polarity transients to −50 V. |
