HX7533 from HX hengjiaxing, in a SOT-23. 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 | GND | power_in | Chip ground reference. |
| 3 | VIN | power_in | Unregulated supply input. Absolute max 20V; recommended operating up to 18V. Bypass with 10µF to GND close to the pin. |
| 2 | VOUT | power_out | Regulated 3.3V ±3% output, up to 100mA typical (60mA min). Requires 10µF output capacitor to GND for stability. Dropout ~100mV at IOUT=1mA. |
