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 | Input supply voltage. Accepts 7V to 40V for the 5.0V fixed-output LM2575 (up to 60V for LM2575HV). Bypass locally with a 680 uF (or similar) low-ESR aluminum electrolytic to GND. |+| 2 | Output | output | Switching output from the internal 2A power switch. Connects to the external catch diode (e.g. 1N5824 Schottky) to GND and to the output inductor (typ. 33 uH) that feeds the load and output capacitor. |+| 3 | GND | power_in | Device ground reference. Also serves as the thermal path; on the TO-263 package this pin is fused to the tab/heat slug and should tie to a copper pour for heat sinking. |+| 4 | Feedback | input | Output voltage feedback sense input. For the fixed 5.0V version, connect directly to the regulated 5.0V output node (downstream of the inductor and output capacitor) so the internal reference regulates VOUT to 5V. |+| 5 | ON/OFF | input | Active-low TTL-compatible shutdown input. Pull low or leave floating for normal operation; drive high (up to VIN, absolute-max VIN, min -0.3V) to enter low-power standby mode (IQ typ. 50 uA). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | TO-263-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `LM2575S-5.0`+- `LM2575S-5.0LM2575HVS-5.0`+- `LM2575S-5.0LM2575T-5.0`+- `LM2575S-5.0LM2575HVT-5.0`+- `LM2575S-5.0LM2575T-5.0`+- `LM2575S-5.0LM2575HVT-5.0`++## CAD (KiCad official)++- Symbol: `LM2575S-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/lm2575s-5-0-datasheet.pdf) (30 pp, sha256 `b0c31af439f0b6b9`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
