Carries the quiescent current (typ 2.2 mA, max 6 mA for 78L15). |+| 3 | INPUT | power_in | Unregulated DC input. Absolute maximum Vi = 35 V. Recommended input capacitor C1 = 0.33 µF to ground if the regulator is located far from the power-supply filter. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-89 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `78L15`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/78l15-datasheet.pdf) (22 pp, sha256 `3eeae843c9f51425`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
