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 | Device ground return. Sets the reference for the internal bandgap and feedback divider; connect directly to the system ground plane close to the input/output bypass capacitors. |+| 2 | VOUT | power_out | Regulated output voltage (3.3 V for LDL1117S33R). Delivers up to 1.2 A; requires a minimum 4.7 µF output capacitor for stability. The SOT-223 tab is internally connected to this pin and should be tied to the output copper for heatsinking. |+| 3 | VIN | power_in | Unregulated input supply, 2.5 V to 18 V (20 V AMR). Should be bypassed with at least a 1 µF ceramic capacitor placed close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOT-223-4 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `LDL1117S33RS33R`++## CAD (KiCad official)++- Symbol: `LDL1117S33R`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223-4 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/ldl1117s33r.pdf) (20 pp, sha256 `387b4375ad125c24`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
