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 | Input supply pin. Operating range 1.8V to 7V, absolute maximum 9V. Bypass to VSS with a 10µF ceramic capacitor close to the pin. |+| 2 | VSS | power_in | Device ground reference (0V). |+| 3 | CE | input | Chip Enable (active high). VCEH = 1.6V min (up to VIN) enables the regulator; VCEL = 0 to 0.5V places the device in shutdown (turn-off current typ. 0.1µA). CE input current ≤0.5µA. Do not leave floating. |+| 4 | NC | unconnected | No internal connection. Leave open or tie as convenient for the PCB layout. |+| 5 | VOUT | power_out | Regulated output, fixed 2.5V ±2.5% for XC6219B252MR. Supplies up to 300mA (typ) with a 280mV typ dropout at 100mA. Requires a 10µF ceramic output capacitor for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `XC6219B252MRB152MR`+- `XC6219B252MRB182MR`+- `XC6219B252MRB252MR`+- `XC6219B252MRB282MR`+- `XC6219B252MRB302MR`+- `XC6219B252MRB332MR`+- `XC6219B252MRB362MR`+- `XC6219B252MRB502MR`+- `XC6219B252MRB152PR`+- `XC6219B252MRB182PR`+- `XC6219B252MRB252PR`+- `XC6219B252MRB282PR`+- `XC6219B252MRB302PR`+- `XC6219B252MRB332PR`+- `XC6219B252MRB362PR`+- `XC6219B252MRB502PR`++## CAD (KiCad official)++- Symbol: `XC6219B252MR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/xc6219b252mr-datasheet.pdf) (9 pp, sha256 `b0229c0bd1c70b57`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
