XTP2021-250AS2CT

XTX · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

XTP2021-250AS2CT from XTX, in a SOT-23-5. 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 Supply input to the regulator. Operating range 1.8V to 5.5V. Bypass to GND with a 1uF ceramic capacitor.
2 GND power_in Device ground return. Common reference for VIN, VOUT and EN.
3 EN input Enable control input. Drive high to enable the regulator, low to disable (~100nA typical shutdown current with automatic VOUT discharge).
4 NC unconnected No internal connection. Leave floating or tie to GND for mechanical robustness.
5 VOUT power_out Regulated output of the LDO. Fixed 2.5V (+/-2%) for the -250 option, up to 300mA. Requires a 1uF ceramic or tantalum output capacitor for stability.
