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 | VO | power_out | Regulated +5 V output. Typical 5.0 V (4.75 V to 5.25 V) over 7 V ≤ VI ≤ 20 V and 1 mA ≤ IO ≤ 40 mA. Bypass with a 0.1 µF ceramic capacitor to GND close to the pin for stability. |+| 2 | GND | power_in | Common ground reference for both input and output. In the SOT-89 package this pin is also the thermal tab, so its PCB copper acts as the primary heatsink for Ptot up to 800 mW. |+| 3 | VI | power_in | Unregulated positive input supply, 7 V to 20 V for spec compliance (30 V absolute max). Bypass with a 0.33 µF capacitor to GND close to the pin to ensure loop stability and reject line transients. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | CBI |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `78L05UU`++## CAD (KiCad official)++- Symbol: `78L05U`+- 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:** [CBI datasheet](docs/78l05u-datasheet.pdf) (2 pp, sha256 `051ac44ab6bfa721`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
