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 | INPUT | power_in | Unregulated DC input supply. Absolute maximum V_I = 35 V (for V_O = 5-18 V variants). A 0.33 uF ceramic capacitor should be placed close to this pin to ground for stability. |+| 2 | GROUND | power_in | Common ground reference. Internally tied to the exposed DPAK tab, which also serves as the primary thermal path (R_thJC = 8 °C/W for DPAK). |+| 3 | OUTPUT | power_out | Regulated +5 V output, up to 1.5 A (over 1 A with adequate heatsinking). A 0.1 uF ceramic output capacitor is recommended for transient response. |+| 4 | GROUND | power_in | DPAK thermal/ground tab. Electrically connected to pin 2 (GROUND) and is the primary heat-sinking surface for the package. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | DPAK |+| Category | Power Management (PMIC) |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `L7805CDT-TR`+- `L7805CDT-TRCP`+- `L7805CDT-TRCP-TR`+- `L7805CDT-TRCV`++## CAD (KiCad official)++- Symbol: `L7805CDT-TR`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: DPAK (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588884658347630592) (55 pp, sha256 `f7b390b5c05e0aba`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
