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 to 6.0V (absolute max 8V). A 1uF ceramic input capacitor to Vss is recommended close to the pin. |+| 2 | Vss | power_in | Ground reference pin for the regulator. Connect to the system ground plane; the internal 1.5kohm discharge resistor sinks Vout to this pin when CE is low. |+| 3 | CE | input | Chip enable, active high. Drive >=1.5V (up to Vin) to enable the regulator; drive <=0.25V (or leave floating; internal 5Mohm pull-down to Vss) to shut down. In shutdown quiescent current drops to ~0.1uA and Vout is discharged through the internal 1.5kohm resistor. |+| 4 | NC | unconnected | No internal connection. May be left floating or tied to Vss for mechanical stability. |+| 5 | Vout | power_out | Regulated output voltage (2.5V for the '25' suffix), accurate to +/-2%, capable of 500mA continuous output current. A 1uF ceramic output capacitor to Vss is required for stability; discharged through an internal 1.5kohm resistor when CE is low. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `BL8568CB5ATR25`+- `BL8568CB5ATR25CA5TR`+- `BL8568CB5ATR25CB3TR`+- `BL8568CB5ATR25CKETR`++## CAD (KiCad official)++- Symbol: `BL8568CB5ATR25`+- 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/bl8568cb5atr25-datasheet.pdf) (8 pp, sha256 `87eda87a1304f4a6`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
