LP5907MFX-1.8 from Texas Instruments, in a SOT-23-5. 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 | IN | power_in | Input voltage supply (2.2 V to 5.5 V). Connect a 1-µF ceramic capacitor at this input. Absolute max 6 V. |
| 2 | GND | power_in | Common ground. All voltages are referenced to this pin. |
| 3 | EN | input | Enable input. A low voltage (<VIL) turns the regulator off and discharges the output pin to GND through an internal 230-Ω pulldown resistor. A high voltage (>VIH) enables the regulator output. Internal 1-MΩ pulldown holds the regulator off by default. Absolute max 6 V. |
| 4 | N/C | unconnected | No internal electrical connection. |
| 5 | OUT | power_out | Regulated 1.8-V output (up to 250 mA). Connect a minimum 1-µF low-ESR ceramic capacitor to this pin. Connect this output to the load circuit. An internal 230-Ω (typical) pulldown resistor prevents charge remaining on VOUT when the regulator is in shutdown mode (VEN low). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 487 faces against 102 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.
