HX hengjiaxing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23
HX7350 from HX hengjiaxing, in a SOT-23. 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 | Chip ground terminal (芯片接地端), the common return for the regulator. |
| 2 | VOUT | power_out | Chip regulated output; for HX7350 the datasheet gives 5.0 V nominal (4.85 V to 5.15 V at VIN=6 V, IOUT=40 mA) with a minimum output current of 250 mA. |
| 3 | VIN | power_in | Startup input pin; the absolute maximum input voltage is 15 V and the datasheet states regulation is maintained with input up to 12 V. |
