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 | input | Adjust pin for the adjustable-output variant (TLV1117CDCYR). Output voltage is set by an external resistor divider from OUT to ADJ to GND, referenced to VREF = 1.25 V (typ). ADJ pin current is 80 µA typ (120 µA max); change in ADJ pin current is 0.2 µA typ (5 µA max for C-temp) over VIN-VOUT = 1.4 V to 10 V and IOUT = 10 mA to 800 mA. On fixed-voltage TLV1117-xx options this pin becomes GND. |+| 2 | OUT | power_out | Regulated output pin. Provides up to 800 mA. Requires an output capacitor (typ 10 µF tantalum or aluminum electrolytic) with ESR between 0.2 Ω and 10 Ω for stability. Internally tied to pin 4 (tab). |+| 3 | IN | power_in | Unregulated input supply. Recommended operating range for the adjustable TLV1117 is 2.7 V to 15 V; absolute maximum VIN is 16 V. A 10-µF input capacitor is recommended. |+| 4 | OUT | power_out | Thermal tab / large pad; internally connected to the OUT pin (pin 2). Must be soldered to a copper area to spread heat - the DCY package has θJA ≈ 104.3 °C/W. Connect to the same net as pin 2 (VOUT). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-223-4 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `TLV1117CDCYR`+- `TLV1117CDCYRIDCY`+- `TLV1117CDCYRIDCYR`+- `TLV1117CDCYRCDRJR`+- `TLV1117CDCYRIDRJR`+- `TLV1117CDCYRCKVUR`+- `TLV1117CDCYRIKVUR`+- `TLV1117CDCYRCKTTR`+- `TLV1117CDCYRCKCS`+- `TLV1117CDCYRCKCT`+- `TLV1117CDCYRIKCS`++## CAD (KiCad official)++- Symbol: `TLV1117CDCYR`+- Footprint: `Package_TO_SOT_SMD:SOT-223`+- 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/tlv1117cdcyr.pdf) (None pp, sha256 `e202b08a47dd722c`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
