LM2931MX-5.0

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

LM2931MX-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 5V output; needs an output capacitor of at least 100 µF for stability, and the output is short-circuit protected.
2 GND power_in Ground pin, one of four GND pins (2, 3, 6, 7).
3 GND power_in Ground pin, one of four GND pins (2, 3, 6, 7).
4 NC unconnected Not internally connected.
5 NC unconnected Not internally connected.
6 GND power_in Ground pin, one of four GND pins (2, 3, 6, 7).
7 GND power_in Ground pin, one of four GND pins (2, 3, 6, 7).
8 IN power_in Unregulated supply input; operating range up to 26V, with reverse battery and 60V load dump protection.
