Torex Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25
XC6227C181MR-G from Torex Semicon, in a SOT-25. 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; operating input voltage range is 1.7V to 6.0V, and an input capacitor CIN of 1.0µF or higher should be connected between VIN and VSS. |
| 2 | VSS | power_in | Ground pin, the reference for VIN, VOUT and CE. |
| 3 | CE | input | ON/OFF control, active high: CE high level is 1.2V to 6.0V (active), CE low level is VSS to 0.3V (stand-by), and the absolute maximum CE input voltage is VSS-0.3V to 6.5V; the XC6227C type has an internal pull-down so the IC stops when CE is left open. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output; output current up to 700mA (VOUT(T) > 1.5V), with reverse current protection that limits reverse current to 1.5µA (MAX.) when VIN is lower than VOUT, and the absolute maximum rating is VSS-0.3V to 6.5V. |
