Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Chip ground terminal. |
| 2 | VIN | power_in | Input supply terminal; for HX7333 (3.3V) operates with VIN from 4.3V up to a 12V maximum input voltage (absolute maximum 15V). |
| 3 | VOUT | power_out | Regulated output terminal of 3.3V (3.201V to 3.399V at VIN=4.3V, IOUT=40mA) with at least 250mA output current. |
