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, 2.5 V to 36 V (absolute max 40 V). A ceramic input capacitor of 1.0 µF or greater is recommended between VIN and VSS. |+| 2 | VSS | power_in | Device ground / common return for VIN, VOUT and CE. All voltages in the datasheet are referenced to this pin. |+| 3 | CE | input | Active-high chip enable. VCE ≥ 1.5 V (up to VIN) turns the regulator on; VCE ≤ 0.3 V forces standby (ISTBY ≤ 0.5 µA). Absolute-max VCE is −0.3 to 33 V. On the 'B' option this input has an internal pull-down resistor, and when the regulator is disabled an internal ~150 Ω resistor discharges COUT. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to VSS; do not use for signal routing. |+| 5 | VOUT | power_out | Regulated 3.3 V output, up to 300 mA continuous (current limit 350-600 mA, short-circuit current typ. 100 mA). Requires an output capacitor of 1.0 µF or greater to VSS for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `CJ6376B33MM`+- `CJ6376B33MMC`+- `CJ6376B33MMY`+- `CJ6376B33MMF`+- `CJ6376B33MMR`+- `CJ6376B33MG`+- `CJ6376B33MGW`+- `CJ6376B33MGL`++## CAD (KiCad official)++- Symbol: `CJ6376B33M`+- 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:** [Changjing datasheet](docs/cj6376b33m-datasheet.pdf) (9 pp, sha256 `a7cfa923a8e0132f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
