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 | Supply input. Operating range 1.8V to 8V; absolute maximum -0.3V to +10V. Bypass with a 1µF ceramic capacitor to GND close to the pin. |+| 2 | GND | power_in | Device ground reference for the regulator and shutdown logic. |+| 3 | SHDN | input | Active-high shutdown control input. High (VIH ≥ 1.2V) enables the LDO; low (VIL ≤ 0.4V) shuts it down (typ 1µA shutdown quiescent current). Input current ≤1µA. Do not leave floating. |+| 4 | NC | unconnected | Not connected. Leave floating or tie to GND; no internal function. |+| 5 | VOUT | power_out | Regulated 5.0V output (UM1560S-50), ±2.5% accuracy, 300mA guaranteed with 450mA typical current limit. Requires 1µF output capacitor for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Union Semiconductor |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `UM1560S-50S`+- `UM1560S-50P`+- `UM1560S-50DA`+- `UM1560S-50DB`++## CAD (KiCad official)++- Symbol: `UM1560S-50`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Union Semiconductor datasheet](docs/um1560s-50-datasheet.pdf) (24 pp, sha256 `dbe4313ebf61b9cd`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
