Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | IN | power_in | Unregulated input supply. Operating range 6-26V (absolute max 45V). Requires a bypass capacitor (typ. 47µF) to ground close to the pin. |+| 2 | GND | power_in | Ground return. On SOT-223 the tab is electrically connected to GND and should be soldered to a copper area for thermal dissipation. |+| 3 | OUT | power_out | Regulated 5.0V LDO output, up to 1A. Requires a minimum 22µF output capacitor for stability. Internally current-limited (~1.9A typ short-circuit) and thermally protected. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI LM2940IMP 5 0 TR |+| Package | SOT-223-3L |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `LM2940IMP-5.0IMP-5.0/TR`+- `LM2940IMP-5.0CMP-5.0/TR`+- `LM2940IMP-5.0IT-5.0`+- `LM2940IMP-5.0CT-5.0`+- `LM2940IMP-5.0IS-5.0/TR`+- `LM2940IMP-5.0CS-5.0/TR`+- `LM2940IMP-5.0MDT-5.0/TR`+- `LM2940IMP-5.0DQ4-5.0/TR`++## CAD (KiCad official)++- Symbol: `LM2940IMP-5.0`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223-3L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI LM2940IMP 5 0 TR datasheet](docs/lm2940imp-5-0-datasheet.pdf) (11 pp, sha256 `06df9640720139f8`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
