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 | Vout | power_out | Regulated 5V output. Typical VO=5V (min 4.95V, max 5.05V) at TJ=25°C. Maximum output current 150mA. Requires a 0.1µF ceramic output capacitor (CO) close to the pin for stability. |+| 2 | GND | power_in | Common ground reference for both input and output. Also serves as the thermal path in SOT-89 via the enlarged center pad/tab. |+| 3 | INPUT | power_in | Unregulated DC input supply. Absolute maximum VI=35V (for VO=3.3~18V variants) or 40V (VO=24V variant). Typical dropout voltage 1.7V. A 0.33µF input capacitor (C1) is recommended near the pin if the regulator is far from the bulk supply filter. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `78L05-150`+- 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/78l05-150-datasheet.pdf) (17 pp, sha256 `fe2f4e8f0d975d52`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
