# XC6219B332MR

**UMW** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

XC6219B332MR from UMW, in a SOT-23-5. Pinout and pin descriptions extracted from the datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Regulator input supply. Operating range 1.8V to 7V (absolute max 9V). Bypass to VSS with a 10µF ceramic capacitor (Ci). |
| 2 | VSS | power_in | Ground / negative supply reference for the regulator. |
| 3 | CE | input | Chip enable (active high). VCEH ≥ 1.6V enables the regulator; VCEL ≤ 0.5V (e.g. tied to VSS) shuts it down (turn-off current typ 0.1µA). CE input current ≤0.5µA for VCE = 0V to VIN. Do not leave floating. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net; not electrically bonded to the die. |
| 5 | VOUT | power_out | Regulated 3.3V output (±2.5%). Delivers up to 300mA typical with Vin=4.3V. Requires a 10µF ceramic output capacitor (Co) to VSS. Dropout ~35mV at 10mA, ~280mV at 100mA. |
