HX7536 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 datasheet gives no separate electrical limit for this pin. |
| 2 | VOUT | power_out | Regulated output pin; for the HX7536 (3.6 V version) the datasheet specifies 3.492 V to 3.708 V output at VIN=5 V and IOUT=1 mA, and output current of at least 60 mA (100 mA typical) at VIN=5.6 V. |
| 3 | VIN | power_in | Input pin (labelled 'startup input' in the datasheet); the electrical characteristics limit the input voltage to 18 V, with a 20 V absolute maximum input voltage rating. |
