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 | ADJ/GND | power_in | Ground pin for fixed-voltage variants (TLV1117-33 = 3.3-V fixed). On the adjustable TLV1117 this pin is the ADJ feedback input for the external resistor divider; on fixed-output devices such as the -33 it functions as the device ground reference. |+| 2 | OUTPUT | power_out | Regulated 3.3-V output. Supplies up to 800 mA. Requires an output capacitor for stability; place close to the pin. |+| 3 | INPUT | power_in | Unregulated input voltage pin. For the TLV1117-33 the recommended V_IN range is 4.7 V to 15 V (absolute maximum 16 V). Bypass with a capacitor close to the pin. |+| 4 | OUTPUT | power_out | SOT-223 thermal tab, internally connected to OUTPUT (pin 2). Solder to a copper pour for heat sinking and connect to the OUTPUT net. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `TLV1117-33CDCYRDCY`+- `TLV1117-33CDCYRDCYR`+- `TLV1117-33CDCYRDRJ`+- `TLV1117-33CDCYRKVU`+- `TLV1117-33CDCYRKCS`+- `TLV1117-33CDCYRKCT`+- `TLV1117-33CDCYRKTT`++## CAD (KiCad official)++- Symbol: `TLV1117-33CDCYR`+- 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:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tlv1117-33cdcyr.pdf) (39 pp, sha256 `ec710cfae85d9a30`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
