Torex Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25
XC6221B301MR-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 range 1.6V to 6.0V (absolute max 6.5V), with a 1.0μF ceramic input capacitor recommended between VIN and VSS. |
| 2 | VSS | power_in | Ground pin. |
| 3 | CE | input | Active-high ON/OFF control; high is 1.2V to 6.0V and low is 0.3V or less, and for XC6221B (no pull-down) the output is unstable if CE is left open. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output; needs an output capacitor CL for phase compensation (1.0μF or more for 1.40V to 4.00V outputs), and the XC6221B has a CL auto-discharge resistor of 780Ω typ. to VSS when CE is low. |
