QX2304L28TO

QX Micro Devices · DC-DC Converters · TO-92-3

QX2304L28TO from QX Micro Devices, in a TO-92-3. 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.
2 VOUT input Output voltage feedback input (max 7 V on VOUT), connected to the output capacitor and load.
3 LX output Drain of the internal power switch, connected to the inductor; max 7 V and 1000 mA absolute maximum, typical current limit 800 mA.
