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 the fixed-output version (SPX1587AT-3.3). Reference return for the internal 1.25V bandgap. On adjustable versions this pin is the ADJ feedback node instead. Tab is electrically connected to VOUT, not this pin. |+| 2 | VOUT | power_out | Regulated 3.3V output, 0 to 3A. Requires a stability capacitor to GND (10µF electrolytic or 4.7µF solid tantalum minimum; 22µF/10µF when ADJ pin is bypassed). Tab of TO-263 is electrically connected to this pin. |+| 3 | VIN | power_in | Unregulated input supply, 4.75V to 10V for the 3.3V fixed version. Maximum input voltage 10V; maximum input-to-output differential 8.8V. An input bypass capacitor is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MaxLinear |+| Package | TO-263-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `SPX1587AT-L-3-3AT-3.3`+- `SPX1587AT-L-3-3T-3.3`+- `SPX1587AT-L-3-3AU-3.3`+- `SPX1587AT-L-3-3U-3.3`+- `SPX1587AT-L-3-3AR-3.3`+- `SPX1587AT-L-3-3R-3.3`++## CAD (KiCad official)++- Symbol: `SPX1587AT-L-3-3`+- Footprint: `Package_TO_SOT_SMD:TO-263-2`+- 3D model: TO-263-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MaxLinear datasheet](docs/spx1587at-l-3-3-datasheet.pdf) (7 pp, sha256 `22e31b3a069bec1b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
