XC6221A182MR-G

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

XC6221A182MR-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. Operating range 1.6V to 6.0V (absolute max VSS-0.3 to +6.5V). Bypass with a 1.0uF ceramic capacitor to VSS.
2 VSS power_in Ground reference for the regulator.
3 CE input Chip-enable ON/OFF control, active HIGH. VCEH >=1.2V (max 6.0V) enables the regulator; VCEL <=0.3V places the device in stand-by (<0.1uA). XC6221A has no internal pull-down, so leaving CE open is an undefined state, tie CE explicitly high or low.
4 NC unconnected No internal connection. May be left floating or tied to any potential.
5 VOUT power_out Regulated output. Fixed 1.8V nominal for the '182' option (Standard accuracy, +/-2% at Vout >= 1.50V). Rated 200mA (up to 250mA typ). Requires >=1.0uF ceramic stabilization capacitor (CL) to VSS. XC6221A has no CL auto-discharge, output decays through R1/R2 divider when disabled.
