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 | GND | power_in | Common ground return for the regulator. Reference node for both the negative input and negative output voltages. |+| 2 | INPUT | power_in | Unregulated negative supply input (VI). For the 79L05 variant the input range is roughly -7V to -20V (absolute max -35V). A 0.33 µF ceramic bypass capacitor to GND is recommended close to the pin. |+| 3 | VOUT | power_out | Regulated negative output voltage (VO = -5V typ, -4.95V to -5.05V) sourcing up to 150mA (absolute max IO = 0.15A). A 0.1 µF output capacitor to GND is recommended for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `79L05-150`+- 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/79l05-150-datasheet.pdf) (15 pp, sha256 `ac755340c55db95e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
