STEF05SGR from STMicroelectronics, in a SOT-23-8. 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 | ILim | input | Current limit programming pin; connect external RLim resistor between this pin and Source to set the overcurrent threshold (voltage range: -0.3 to 25 V). |
| 2 | En/Fault | bidirectional | Enable/fault status pin; leave floating to enable device, pull to ground to disable, outputs intermediate state (1.2-1.45 V typ.) on thermal shutdown. |
| 3 | dV/dt | input | Soft-start timing control; connect optional external capacitor to ground to extend output ramp-up time beyond default 1.35 ms (voltage range: -0.3 to 7 V). |
| 4 | GND | power_in | Ground connection. |
| 5 | Source/VOUT | output | Power MOSFET source and fuse output; output voltage clamped to 5.7 V typical with current limited according to RLim setting. |
| 6 | Source/VOUT | output | Power MOSFET source and fuse output; output voltage clamped to 5.7 V typical with current limited according to RLim setting. |
| 7 | VCC | power_in | Positive supply voltage input; recommended operating range 3.5 to 5.5 V (absolute maximum rating: -0.3 to 25 V). |
| 8 | VCC | power_in | Positive supply voltage input; recommended operating range 3.5 to 5.5 V (absolute maximum rating: -0.3 to 25 V). |
