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 DC input supply. Operating range 4.5V to 60V for the HV variant (LM2576HV); absolute maximum 63V. Bypass close to the pin with the input capacitor (CIN). |+| 2 | Output | output | Switching output of the internal 3A NPN power switch. Connects to the inductor L1 and the cathode of the catch diode (e.g. 1N5822). Withstands transient down to -1V vs. GND. |+| 3 | GND | power_in | Device ground reference. Common return for input, output, feedback divider and ON/OFF pin. Tie directly to the ground plane; the TO-263 tab is also connected to GND. |+| 4 | Feedback | input | Output voltage feedback input to the internal error amplifier (1.23V bandgap reference). For the -5.0 fixed variant, tie directly to the regulated +5V output node; the internal divider sets VOUT = 5.0V ±4%. |+| 5 | ON/OFF | input | Active-low TTL shutdown input. Regulator is enabled when this pin is Low or left floating; pulling it High (up to +VIN, min -0.3V) puts the device into low-power standby (~50µA typical). Do not exceed VIN. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | TO-263-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `LM2576HVS-5.0S`+- `LM2576HVS-5.0T`++## CAD (KiCad official)++- Symbol: `LM2576HVS-5.0`+- Footprint: `Package_TO_SOT_SMD:TO-263-2`+- 3D model: TO-263-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/lm2576hvs-5-0-datasheet.pdf) (18 pp, sha256 `10275fb18a78ad8b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
