# HX7150

**HX(hengjiaxing)** · Linear Voltage Regulators (LDO) · SOT-23

HX7150 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; the common reference for the regulator, which is rated for a maximum input voltage of 18 V. |
| 2 | VOUT | power_out | Chip output terminal that delivers the regulated output voltage (5.0 V nominal for the 5.0 V variant) with a minimum output current of 60 mA at VIN = 7 V. |
| 3 | VIN | power_in | Input terminal for the supply voltage, rated up to 18 V maximum (absolute maximum input voltage 20 V). |
