HX7144 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 (芯片接地端). Common return for the input capacitor, output capacitor, and load. Reference for the internal bandgap Vref. |
| 2 | VOUT | power_out | Regulated output (芯片输出端). Nominal 4.4V ±3% for HX7144, sourcing up to 100 mA (typ). Requires a 10 µF ceramic/electrolytic decoupling capacitor to GND. |
| 3 | VIN | power_in | Unregulated input supply (启动输入端). Accepts up to 18V (20V absolute max). Bypass with a 10 µF capacitor close to the pin. For HX7144 operation, VIN ≥ 5.4V ensures line regulation spec. |
