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 voltage input, 2.0 V to 6.0 V (8 V abs max). Bypass with 1 uF ceramic to Vss close to the pin. |+| 2 | Vss | power_in | Ground / negative supply return for the regulator and reference. |+| 3 | CE | input | Chip enable. Drive high (Vceh >= 1.5 V, up to Vin) to enable the regulator; drive low (Vcel <= 0.25 V) to shut down (Istandby = 0.1 uA typ). When CE is low a 1.5 kΩ discharge resistor is switched across Vout. Internal ~500 kΩ pull-down to Vss. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to Vss. |+| 5 | Vout | power_out | Regulated output, 1.8 V (±2%) for the -18 option, 300 mA max output current. Bypass with 1 uF ceramic to Vss for stability. Discharged through internal 1.5 kΩ when CE is low. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `BL8563-18PRA`+- `BL8563-18PRAQ`+- `BL8563-18PRARM`+- `BL8563-18PRACKETR`+- `BL8563-18PRACKFTR`++## CAD (KiCad official)++- Symbol: `BL8563-18PRA`+- 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:** [BL Shanghai Belling datasheet](docs/bl8563-18pra-datasheet.pdf) (9 pp, sha256 `c6fe9ba9214e8e33`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
