Sources up to 100 mA. Requires a 0.1 µF ceramic capacitor to GND for stability and transient response. |+| 2 | GND | power_in | Common/ground reference. Return path for input current, output current, and quiescent current (~2 mA typ). |+| 3 | INPUT | power_in | Unregulated DC input, typically 7.5 V to 20 V (absolute max 35 V for VO=3.3-18 V variants). Requires a 0.33 µF ceramic input capacitor to GND close to the pin; dropout ~1.7 V above VO. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SO-8 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `L78L05A`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SO-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/l78l05a-datasheet.pdf) (22 pp, sha256 `3eeae843c9f51425`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
