ST730M33R from STMicroelectronics, in a SOT-23-5. 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 | VOUT | output | Regulated output voltage, 3.3 V fixed, 300 mA maximum output current. |
| 2 | GND | power_in | Ground reference voltage. |
| 3 | VIN | power_in | Input voltage supply, operating range 2.5 V to 28 V. |
| 4 | NC | unconnected | Not internally connected in the fixed version ST730M33R. |
| 5 | EN | input | Enable pin logic input; Low state = shutdown, High state = active; do not leave floating. |
