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 | IN | power_in | Regulator input supply, 2.5V to 18V operating (absolute max 24V). Place a 1µF ceramic input capacitor as close to IN and GND as possible for best transient response. |+| 2 | GND | power_in | Regulator ground. Common reference for input, output and enable. |+| 3 | EN | input | Active-high enable input. Drive EN high (≥1.5V) to enable the regulator, drive low (≤0.3V) to shut it down (standby current 0.2µA typ). Do not float; tie to IN if unused. Absolute max VEN = 24V. |+| 4 | NC | unconnected | No internal connection. May be left floating; connecting to GND improves thermal performance. |+| 5 | OUT | power_out | Regulated 3.3V output, up to 300mA. Requires a 1µF ceramic output capacitor between OUT and GND placed as close to the pins as possible to maintain stability and transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-23-5L |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `CJ6330B33MBxxM`+- `CJ6330B33MAxxMF`+- `CJ6330B33MAxxMR`+- `CJ6330B33MAxxM`+- `CJ6330B33MAxxMC`+- `CJ6330B33MAxxMY`+- `CJ6330B33MAxxP`+- `CJ6330B33MAxxPT`+- `CJ6330B33MAxxPL`+- `CJ6330B33MAxxG`+- `CJ6330B33MAxxGF`++## CAD (KiCad official)++- Symbol: `CJ6330B33M`+- 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/cj6330b33m-datasheet.pdf) (35 pp, sha256 `ef1dd74aa3b7af80`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
