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

XC6227C121MR from TECH PUBLIC, 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 | Input of supply voltage, 1.7 V to 6 V operating (absolute maximum 6.5 V). |
| 2 | GND | power_in | Ground (VSS). |
| 3 | EN | input | Enable control input (CE); VIH 1.2 V min on rising, VIL 0.5 V max on falling, absolute maximum 6.5 V. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Output of the regulator, up to 700 mA output current. |
