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 4.75V to 40V (LM2596) / 4.75V to 60V (LM2596HV); absolute max 45V / 63V. Bypass close to pin with a low-ESR input capacitor (typ. 680 uF). |+| 2 | Output | output | Switching output node of the internal power switch. Connects to the external catch diode (e.g. 1N5824 Schottky) cathode and to the output inductor (typ. 33 uH). Rated 3A continuous load current; do not exceed -1V below ground in steady state. |+| 3 | GND | power_in | Device ground reference. Tie directly to the system ground plane; carries return current for both control and power stages. |+| 4 | Feedback | input | Output voltage feedback sense pin. For the fixed 5.0V version this pin ties directly to the regulated output; internal divider sets Vout = 5V. Absolute max -0.3V to +25V. |+| 5 | ON/OFF | input | Active-low TTL-compatible shutdown. Regulator is enabled when this pin is Low or left floating; pulled High (up to +25V) forces low-power standby (IQ ~ 80 uA typ.). Absolute max -0.3V to +25V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | TO-263-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `LM2596S-5.0`+- `LM2596S-5.0LM2596HVS-5.0`+- `LM2596S-5.0LM2596T-5.0`+- `LM2596S-5.0LM2596HVT-5.0`++## CAD (KiCad official)++- Symbol: `LM2596S-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/lm2596s-5-0-datasheet.pdf) (28 pp, sha256 `26d031e9696524e9`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
