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 | Vss/ADJ | power_in | Ground pin for fixed-output versions (Vss). On the AH1117-ADJ variant this pin functions as the ADJ feedback input, referenced to the 1.25V internal bandgap. For AH1117CLTR18 (fixed 1.8V) this pin is the device ground. |+| 2 | Vout | power_out | Regulated output voltage. For AH1117CLTR18 the nominal output is 1.8V ±2% at up to 1A load, with 10mV typical load regulation. A 10uF tantalum output capacitor is recommended for stability. |+| 3 | Vin | power_in | Supply voltage input. Recommended operating range up to 12V (absolute max 15V). For 1.8V output, minimum Vin ≈ 3.3V to guarantee regulation; a 10uF tantalum input bypass capacitor is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-223-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `AH1117CLTR12`+- `AH1117CLTR15`+- `AH1117CLTR18`+- `AH1117CLTR25`+- `AH1117CLTR33`+- `AH1117CLTR50`+- `AH1117CLTRAD`+- `AH1117CLTR18COTR12`+- `AH1117CLTR18COTR15`+- `AH1117CLTR18COTR18`+- `AH1117CLTR18COTR25`+- `AH1117CLTR18COTR33`+- `AH1117CLTR18COTR50`+- `AH1117CLTR18COTRAD`++## CAD (KiCad official)++- Symbol: `AH1117CLTR18`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [BL Shanghai Belling datasheet](docs/ah1117cltr18-datasheet.pdf) (8 pp, sha256 `0ee1c0c75939cf2d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
