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 return for the regulator. On the fixed-voltage CJT1117B-5.0 this pin is tied to the internal feedback divider and must be connected to system ground. |+| 2 | OUTPUT | power_out | Regulated 5.0V output (4.9V min, 5.1V max over 10mA-1A load, 6.5V-12V input). Requires a 22uF tantalum (or equivalent) output capacitor for stability. Delivers up to 1A continuous. |+| 3 | IN | power_in | Unregulated input voltage. Recommended operating input is up to 15V; absolute max 20V. For 5.0V output requires VIN >= 6.5V to stay in regulation. A 10uF tantalum input bypass capacitor is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `CJT1117B-5.0`++## CAD (KiCad official)++- Symbol: `CJT1117B-5.0`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Jiangsu datasheet](docs/cjt1117b-5-0-datasheet.pdf) (8 pp, sha256 `b0ed54cb65b16a17`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
