HX3216P302MR 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 specifies no electrical limit for this pin. |
| 2 | VOUT | power_out | Regulated output of 3.0 V with a tolerance of ±2.5% (2.925 V to 3.075 V), giving at least 60 mA and 100 mA typical output current at VIN = 5 V. |
| 3 | VIN | power_in | Input terminal, rated at a maximum input voltage of 10 V in the model selection table and 12 V as the absolute maximum rating. |
