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. Operating range 2.0V-6V (absolute max 8V). Recommend 1uF ceramic decoupling capacitor to Vss. |+| 2 | Vss | power_in | Ground return pin for the regulator. |+| 3 | CE | input | Chip enable. Drive high (Vceh ≥ 1.5V, up to Vin) to enable the regulator; drive low (Vcel ≤ 0.25V) to enter shutdown (Istandby 0.1uA typ) and activate the 1.5kΩ output discharge path. Internally pulled down through ~5MΩ (Rcepd). |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to ground on the PCB. |+| 5 | Vout | power_out | Regulated 1.8V output (±2% accuracy, 500mA max, 300mV typ dropout at 300mA). Requires 1uF ceramic output capacitor for stability. Actively discharged through ~1.5kΩ when CE is low. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `BL8568CB5ATR18`+- `BL8568CB5ATR18CA5TR`+- `BL8568CB5ATR18CB3TR`+- `BL8568CB5ATR18CKETR`++## CAD (KiCad official)++- Symbol: `BL8568CB5ATR18`+- 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/bl8568cb5atr18-datasheet.pdf) (8 pp, sha256 `87eda87a1304f4a6`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
