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 positive DC input. Recommended 7 V to 25 V for 5 V output; absolute maximum 35 V. A 0.33 µF ceramic input decoupling capacitor to GND is recommended close to the pin to ensure stability. |+| 2 | GND | power_in | Common ground for both input and output. On TO-252 (DPAK) this pin is electrically connected to the exposed thermal tab, which should be soldered to a copper heatsink pad to dissipate power (RthJC = 8 °C/W, RthJA = 100 °C/W for TO-252). |+| 3 | OUT | power_out | Regulated +5 V output (4.8 V-5.2 V typ. at TJ=25 °C, IO=500 mA). Sources up to 1.2 A subject to thermal and SOA limits. A 0.1 µF ceramic output capacitor to GND is recommended for transient response and stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | TO-263 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `L7805CD2TD2T`+- `L7805CD2TCD2T`+- `L7805CD2TCV`+- `L7805CD2TD2T-B`+- `L7805CD2TCD2T-B`++## CAD (KiCad official)++- Symbol: `L7805CD2T`+- Footprint: `Package_TO_SOT_SMD:TO-263-2`+- 3D model: TO-263 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/l7805cd2t-datasheet.pdf) (18 pp, sha256 `187ff89cc4c93f6a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
