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 | VIN | power_in | Unregulated input supply. Operating range up to 60V (63V absolute max). Bypass locally with a 100uF/75V aluminum electrolytic close to the pin. |+| 2 | OUTPUT | output | Switch (SW) output pin. Internal power switch node that drives the external inductor and catch diode. Saturation voltage typ 1.4V at 3A; supports up to 3A load with 12V fixed output. |+| 3 | GND | power_in | Device ground reference. Also the thermal path for the TO-263 tab; connect to a ground plane for heat dissipation. |+| 4 | FEEDBACK | input | Regulation feedback input. On the fixed 12V version this pin connects directly to the regulated output to sense 12V. Internal reference is 1.23V (ADJ version divider tap). |+| 5 | ON/OFF | input | Active-low TTL-compatible enable/shutdown input. Logic low (<=0.8V) enables the regulator; logic high (>=2.4V, up to VIN) puts it in low-power standby (typ 50uA). Do not exceed VIN. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | TO-263-5L |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `LM2576HVS-12`++## CAD (KiCad official)++- Symbol: `LM2576HVS-12`+- Footprint: `Package_TO_SOT_SMD:TO-263-2`+- 3D model: TO-263-5L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TECH PUBLIC datasheet](docs/lm2576hvs-12-datasheet.pdf) (6 pp, sha256 `c2f526f1b6543179`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
