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 | VIN | power_in | Unregulated positive input supply. Recommended operating range up to 15V (abs max 18V). For the 5.0V variant, VIN must be at least ~6.5V for full regulation (dropout ~1.2V at 1A). Bypass with a 10uF capacitor close to the pin. |+| 2 | GND | power_in | Device ground reference. On fixed-output versions this pin sets the 0V reference for the internal error amplifier. Should be tied to system ground with a low-impedance return path. |+| 3 | VOUT | power_out | Regulated 5.0V output (tolerance +/-2%, 4.900V min / 5.100V max). Supplies up to 1.0A on the 'A' variant. Requires a minimum 10uF output capacitor for stability; MLCC supported per the ESR SOA graph. |+| 4 | TAB | power_out | Large SOT-223 heat-slug tab, internally connected to VOUT. Solder to a copper pour tied to the VOUT net for thermal dissipation (theta_JA = 165 C/W for SOT-223). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UTC Unisonic Tech |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `LD1117AG-50-AA3-D-RAA3-A-R`+- `LD1117AG-50-AA3-D-RAA3-B-R`+- `LD1117AG-50-AA3-D-RAA3-C-R`+- `LD1117AG-50-AA3-D-R`+- `LD1117AG-50-AA3-D-RAA3-A-T`+- `LD1117AG-50-AA3-D-RAA3-B-T`+- `LD1117AG-50-AA3-D-RAA3-C-T`+- `LD1117AG-50-AA3-D-RAA3-D-T`+- `LD1117AG-50-AA3-D-RAB3`+- `LD1117AG-50-AA3-D-RTA3`+- `LD1117AG-50-AA3-D-RTF3`+- `LD1117AG-50-AA3-D-RTN3`+- `LD1117AG-50-AA3-D-RTND`+- `LD1117AG-50-AA3-D-RT2Q`+- `LD1117AG-50-AA3-D-RTQ2`+- `LD1117AG-50-AA3-D-RTQ3`+- `LD1117AG-50-AA3-D-RAE5-G`+- `LD1117AG-50-AA3-D-RAF5-G`+- `LD1117AG-50-AA3-D-RS08`+- `LD1117AG-50-AA3-D-RSH2`+- `LD1117AG-50-AA3-D-RP5060-R`++## CAD (KiCad official)++- Symbol: `LD1117AG-50-AA3-D-R`+- 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:** [UTC Unisonic Tech datasheet](docs/ld1117ag-50-aa3-d-r-datasheet.pdf) (None pp, sha256 `cc56230fa080b180`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
