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 reference for the fixed-voltage (5 V) version. This pin is labeled ADJ/GND in the datasheet; on the -50 fixed-output variant it is tied to the internal reference return and must be connected to system ground. |+| 2 | VOUT | power_out | Regulated 5-V output. Typical VOUT = 5.0 V (4.90 V to 5.10 V over line/load, TLV1117-50I). Sources up to 800 mA. Requires an output capacitor with ESR between 0.2 Ω and 10 Ω (10-µF tantalum/aluminum electrolytic recommended) for stability. |+| 3 | VIN | power_in | Unregulated input supply. Recommended VIN = 6.4 V to 15 V for the 5-V option (headroom above VOUT + dropout). Absolute maximum continuous input voltage is 16 V. A 10-µF input capacitor is recommended. |+| 4 | VOUT | power_out | Tab pin, electrically connected to the VOUT node and serving as the primary thermal path. Should be soldered to a copper pour tied to VOUT to sink the regulator's dissipated power. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-223-4 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `TLV1117-50IDCYR50IDCY`+- `TLV1117-50IDCYR50IDCYR`+- `TLV1117-50IDCYR50CDCY`+- `TLV1117-50IDCYR50CDCYR`+- `TLV1117-50IDCYR50CKVUR`+- `TLV1117-50IDCYR50IKVUR`+- `TLV1117-50IDCYR50CDRJR`+- `TLV1117-50IDCYR50IDRJR`+- `TLV1117-50IDCYRCKCS`+- `TLV1117-50IDCYRCKCT`+- `TLV1117-50IDCYRCKTTR`+- `TLV1117-50IDCYRIKTTR`++## CAD (KiCad official)++- Symbol: `TLV1117-50IDCYR`+- 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:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tlv1117-50idcyr.pdf) (35 pp, sha256 `379f0597207846a7`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
