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 | Unregulated power input. Operating range 2.0V to 7.0V (absolute max VSS+8V). Bypass to VSS with a 1µF low-ESR ceramic capacitor placed close to the pin. |+| 2 | VSS | power_in | Device ground reference (negative supply return). Common return for input and output capacitors. |+| 3 | CE | input | Chip Enable / shutdown control, TTL-logic input. VCE ≥ 1.5V enables the regulator (max = VIN); VCE ≤ 0.3V puts the part into shutdown (ISTBY ≤ 0.1µA). Do not leave floating. |+| 4 | NC | unconnected | No internal connection. May be left floating or tied to VSS for mechanical robustness. |+| 5 | VOUT | power_out | Regulated 2.5V output (±2% typ.), up to 300mA. Requires a 1µF low-ESR ceramic output capacitor to ground for stability. Built-in current-limit and short-circuit protection (IShort ≈ 50mA when VOUT is shorted to VSS). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-23-5L |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `CJ6206B25MM`+- `CJ6206B25MN`+- `CJ6206B25MP`+- `CJ6206B25MPT`+- `CJ6206B25MF`++## CAD (KiCad official)++- Symbol: `CJ6206B25M`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Changjing datasheet](docs/cj6206b25m-datasheet.pdf) (10 pp, sha256 `c8cf1bdd746d4b52`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
