XC6223H331MR-G

Torex Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25

XC6223H331MR-G from Torex Semicon, in a SOT-25. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Power input pin, 1.6 V to 5.5 V. Bypass to VSS with a 1.0 µF (CIN) ceramic capacitor placed close to the pin. Absolute max VSS-0.3 V to +7.0 V.
2 VSS power_in Ground reference for the regulator. Common return for VIN, VOUT, and CE decoupling networks.
3 CE input ON/OFF (chip enable) control input, active high. H (1.0 V ≤ VCE ≤ 5.5 V) = Operation ON; L (0 V ≤ VCE ≤ 0.3 V) = stand-by. XC6223H has an internal CE pull-down resistor so an OPEN pin holds the device OFF.
4 NC unconnected No internal connection. Leave floating or tie as convenient for layout.
5 VOUT power_out Regulated 3.3 V output (±1%), up to 300 mA (400 mA current limit). Requires a CL = 1.0 µF ceramic stabilization capacitor; low-ESR ceramics are supported. In stand-by, the CL discharge switch quickly pulls VOUT down to VSS.
