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 | OUTPUT | power_out | Regulated positive voltage output. Delivers a fixed 15V (±5%) at up to 100mA. A 0.1µF (min 0.01µF) output capacitor is recommended for stability and to limit high-frequency noise. |+| 2 | GND | power_in | Common ground reference for input and output. On the SOT-89 R package this pin also serves as the thermal tab (large metal pad on the underside) for heat sinking into the PCB copper. |+| 3 | INPUT | power_in | Unregulated positive supply input. For the AS78L15 variant Vin must be at least ~17.5V for regulation and is rated up to 36V absolute maximum (30V recommended operating). A 0.33µF input capacitor is recommended, especially when the regulator is located far from the bulk supply. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-89 |+| Category | Power Management ICs |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `AS78L15RTR-E1`+- `AS78L15RTR-E1R`+- `AS78L15RTR-E1Z`+- `AS78L15RTR-E1M`++## CAD (KiCad official)++- Symbol: `AS78L15RTR-E1`+- 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:** [Diodes Incorporated datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8560107478970368000) (17 pp, sha256 `dae32ffe04830377`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
