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. Recommended operating range 7V to 45V (5V version); absolute maximum 45V. Bypass with a low-ESR input capacitor close to the pin. |+| 2 | Output | output | Switching output pin - internal power BJT emitter. Connects to the external catch diode cathode and inductor to form the buck power stage. Delivers up to 3A load current with typical saturation voltage of 1.2V at 3A. |+| 3 | GND | power_in | Ground reference for the device. Tie to the system ground plane; also serves as the thermal path together with the package tab. |+| 4 | FB | input | Output voltage feedback pin. Internally connected to the fixed-5V resistor divider on the 5V version; connect directly to the regulator output node. Feedback bias current typically 10nA. |+| 5 | ON/OFF | input | TTL-compatible shutdown control. Regulator is ON when the pin is low (<1.3V typ) or left floating; regulator enters standby (IQ ≈ 80µA) when driven high (>2.0V). Absolute max Vin+0.3V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Techcode Semicon |+| Package | TO-263-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `TD1501S50S50`+- `TD1501S50L50`+- `TD1501S50T50`++## CAD (KiCad official)++- Symbol: `TD1501S50`+- 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:** [Techcode Semicon datasheet](docs/td1501s50-datasheet.pdf) (18 pp, sha256 `c0e40074baddb703`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
