XC6219B302MR-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's absolute maximum supply voltage is 8V (range -0.3V to 8V), and a 10uF input capacitor should be connected between VIN and GND. |
| 2 | GND | power_in | Ground pin; keep the resistance of the VIN-to-GND wiring low, and place the input and output capacitors as close to the IC as possible. |
| 3 | CE | input | Chip enable pin that shuts down the internal circuitry; the datasheet recommends driving it with either a VIN or VSS voltage, and its logic polarity is set by the selected option. |
| 4 | NC | unconnected | No connection; the datasheet lists this pin as no connection. |
| 5 | VOUT | power_out | Regulated output pin; an output capacitor of at least 10uF should be connected as close as possible to VOUT and GND for phase compensation. |
