XC6902N501PR-G

Torex Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

XC6902N501PR-G from Torex Semicon, in a SOT-89-3. 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 GND power_in Ground reference pin for the negative regulator; the datasheet lists this as the Ground pin for the SOT-89 package.
2 -VIN power_in Negative supply input, with an input voltage range of -2.4 V to -16 V per the datasheet electrical characteristics.
3 -VOUT power_out Negative regulated output, which is -5.0 V nominal for the XC6902N501 variant with ±1.5% accuracy and up to 200 mA maximum output current.
