# XC6219B362MR-MS

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

XC6219B362MR-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 at up to 8V (absolute maximum 8V), and the electrical characteristics are tested with Vin = Vout + 1V, with a 10uF input capacitor recommended between VIN and GND. |
| 2 | GND | power_in | Ground pin; the output capacitor (at least 10uF) and input capacitor (10uF) should be wired as close to the IC as possible, and the VIN-to-GND wiring resistance should be kept low. |
| 3 | CE | input | Chip enable pin that shuts down the internal circuitry; the datasheet advises driving it with either a VIN or VSS voltage, and the CE input current increases while the IC is operating. |
| 4 | NC | unconnected | No connection; the datasheet lists this pin as NC with no function. |
| 5 | VOUT | power_out | Regulated output pin; for this 3.6V part the output is 3.6V ±2% (0.98×Vout to 1.02×Vout) for 1.0mA ≤ Iout ≤ 30mA, and an output capacitor of at least 10uF should be connected as close as possible to this pin and GND. |
