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 | OUTPUT | power_out | Regulated +5 V output. Typ 5.00 V (4.92-5.08 V at Tj=25 C). Capable of up to 300 mA continuous, 500 mA peak. Requires a Co ≈ 0.1 µF ceramic to GND for stability. |+| 2 | GND | power_in | Common ground reference for input and output. Also acts as the thermal/tab connection on SOT-89 (center pad). |+| 3 | INPUT | power_in | Unregulated DC input, 7 V to 20 V typical operating range for the 78L05, absolute max 35 V. Bypass with a Ci ≈ 0.33 µF ceramic to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `78L05-300`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/78l05-300-datasheet.pdf) (15 pp, sha256 `43e8779d625b95a5`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
