XC6227C331PR-G from Torex Semicon, in a SOT-89-5. 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 | CE | input | ON/OFF control: a high level (1.2V to 6.0V) enables the regulator and a low level (VSS to VSS+0.3V) puts it in stand-by, and the XC6227C type has an internal pull-down so an open CE pin stops operation. |
| 2 | VSS | power_in | Ground pin of the regulator, referenced for the VIN, VOUT and CE limits (absolute maximum VIN, VOUT and VCE are VSS-0.3V to 6.5V). |
| 3 | NC | unconnected | No connection. |
| 4 | VIN | power_in | Power input with an operating voltage range of 1.7V to 6.0V, where a 1.0µF ceramic input capacitor CIN between VIN and VSS is recommended for stable input. |
| 5 | VOUT | power_out | Regulated output (3.3V for this XC6227C331 part) that requires a 2.2µF ceramic output capacitor CL for phase compensation, and reverse current from VOUT to VIN is limited to 1.5µA max when VIN is below VOUT. |
