TPS7A4101DGNR from Texas Instruments, in a MSOP-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Regulator output. A capacitor greater than 4.7 µF must be tied from this pin to ground to assure stability. Sources up to 50 mA at the programmed output voltage (VREF to 48 V). |
| 2 | FB | input | Feedback input to the control-loop error amplifier. Used with an external resistor divider to set the output voltage; internal reference VREF = 1.173 V (typ). |
| 3 | NC | unconnected | Not internally connected. This pin must either be left open or tied to GND. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | EN | input | Enable input. VEN >= VEN_HI (1.5 V min) enables the regulator; VEN <= VEN_LO (0.4 V max) disables it. If not used, EN can be connected to IN. VEN must not exceed VIN at any time. |
| 6 | NC | unconnected | Not internally connected. This pin must either be left open or tied to GND. |
| 7 | NC | unconnected | Not internally connected. This pin must either be left open or tied to GND. |
| 8 | IN | power_in | Input supply. Operating range 7 V to 50 V (absolute maximum 55 V). Bypass with a >= 1 µF capacitor to GND close to the pin. |
| 9 | PowerPAD | passive | Exposed thermal pad on the package underside. Internally connected to GND. Solder to the PCB and connect to the GND plane to enhance thermal performance; may be left floating but this is not recommended. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 570 faces against 140 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
