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 positive DC input. Absolute max VI = 35 V for 5-18 V output versions. Recommended input capacitor CI = 0.33 uF close to the pin for stability. Dropout voltage ~2 V at IO = 1 A, so VI should be at least VO + 2 V (typ. 7.5 V min for the 5 V part). |+| 2 | GROUND | power_in | Common ground reference for input and output. Electrically connected to the exposed metal tab of the D2PAK, which serves as the primary heat-sinking surface. Quiescent current (~4.3 mA typ) flows out of this pin. |+| 3 | OUTPUT | power_out | Regulated +5 V output, 4.8-5.2 V over line/load/temperature (A version). Delivers up to 1.5 A peak (typically specified at 1 A) with internal current limiting, SOA and thermal-shutdown protection. Recommended output capacitor CO = 0.1 uF for transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | TO-263-2 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `L7805ABD2T-TRD2T-TR`+- `L7805ABD2T-TRD2T`+- `L7805ABD2T-TRDT-TR`+- `L7805ABD2T-TRDT`+- `L7805ABD2T-TRCV`+- `L7805ABD2T-TRABV`+- `L7805ABD2T-TRCP`+- `L7805ABD2T-TRABP`++## CAD (KiCad official)++- Symbol: `L7805ABD2T-TR`+- Footprint: `Package_TO_SOT_SMD:TO-263-2`+- 3D model: TO-263-2 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/l7805abd2t-tr.pdf) (55 pp, sha256 `f7b390b5c05e0aba`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
