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 | Ground reference pin. Common return for input and output. In negative regulators, this pin is the 0V reference relative to the negative input and negative output. |+| 2 | IN | power_in | Negative unregulated input voltage. Absolute maximum VIN = -35V. Typical operating range -17.5V to -30V for -15V output. Requires a 2.2 uF input bypass capacitor to ground close to the pin. |+| 3 | OUT | power_out | Regulated -15V negative output. Delivers up to -1.5A with adequate heatsinking. Requires a 1 uF output capacitor to ground for stability. Dropout voltage ~2V at 1.5A. |+| TAB | IN | power_in | Exposed metal tab electrically connected to pin 2 (IN) on negative regulators of the 79xx family in TO-252. Serves as the primary thermal path to the PCB copper pour; must be connected to the same net as pin 2 (unregulated negative input). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | YFW |+| Package | TO-252 |+| Category | PMIC |+| Pins | 4 |++## CAD (KiCad official)++- Symbol: `7915`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [YFW datasheet](docs/7915-datasheet.pdf) (4 pp, sha256 `825b5a9a988e5d00`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
