Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4
LM2940IMPX-10 from Texas Instruments, in a SOT-223-4. 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, operating range 6 V to 26 V. |
| 2 | GND | power_in | Ground. |
| 3 | OUT | power_out | Regulated output voltage; requires an output capacitor of at least 22 µF to maintain stability. |
| 4 | GND | power_in | Ground (tab). |
