QX2304L36F from QX Micro Devices, in a SOT-23-5. 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 | EN | input | Active-high enable input; input high level is 0.4*VOUT minimum and input low level is 0.2 V maximum, with standby input current of 1 uA max when EN is low. |
| 2 | VOUT | input | Output voltage feedback pin (tied to the output capacitor); absolute maximum voltage is 7 V. |
| 3 | NC | unconnected | No connection, left floating. |
| 4 | GND | power_in | Ground. |
| 5 | LX | output | Drain of the internal power switch, connected to the inductor; maximum voltage is 7 V and maximum current is 1000 mA. |
