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 | IN | power_in | Regulator input supply. Accepts up to 20 V and up to VOUT+VDO minimum. A 1-uF to 10-uF bypass capacitor is required (especially when placed more than ~6 inches from the input filter cap). Reverse-battery tolerant. |+| 2 | GND | power_in | Ground reference for the regulator. The DCY package brings GND out on pin 2 as well as on the tab (pin 4). |+| 3 | OUT | power_out | Regulated 3.3-V output, 1.5-A capable. Requires a minimum 10-uF ceramic output capacitor for stability; larger caps recommended for large transient loads. |+| 4 | GND (Tab) | power_in | SOT-223 thermal tab, electrically connected to GND. Must be soldered to a PCB copper pour for rated thermal performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `TL1963A-33DCYR`+- `TL1963A-33DCYRDCQ`+- `TL1963A-33DCYRDCQR`+- `TL1963A-33DCYRKTT`+- `TL1963A-33DCYRKTTR`+- `TL1963A-33DCYRKTTT`++## CAD (KiCad official)++- Symbol: `TL1963A-33DCYR`+- 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/tl1963a-33dcyr.pdf) (39 pp, sha256 `4d78d60ab065db02`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
