# XC6219B282MR-MS

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

XC6219B282MR-MS from MSKSEMI, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Power input pin; the datasheet rates the supply voltage from -0.3V to 8V absolute maximum, with input voltage up to 8V. |
| 2 | GND | power_in | Ground pin; the input capacitor (CIN) of 10uF should be connected between VIN and GND, and the output capacitor placed as close as possible to VOUT and GND. |
| 3 | CE | input | Chip enable pin that shuts down the internal circuitry; the datasheet recommends driving it with either a VIN or VSS voltage level. |
| 4 | NC | unconnected | No connection pin. |
| 5 | VOUT | power_out | Regulated output pin; the output capacitor should be at least 10uF and placed as close as possible to VOUT and GND. |
