LP5907MFX-2.5 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. Requires a minimum 1-µF low-ESR ceramic bypass capacitor to GND placed close to the pin for stability. |
| 2 | GND | power_in | Common ground reference for the device. All voltages are referenced to this pin. |
| 3 | EN | input | Active-high enable input. A voltage below VIL (0.4 V) turns the regulator off and discharges VOUT to GND through an internal ~230-Ω pulldown. A voltage above VIH (1.2 V) enables the regulated output. An internal 1-MΩ pulldown holds the regulator off by default. Do not leave floating in noisy environments. |
| 4 | NC | unconnected | No internal electrical connection. May be left floating or tied to GND for mechanical robustness. |
| 5 | OUT | power_out | Regulated 2.5-V output, up to 250 mA. Requires a minimum 1-µF low-ESR ceramic capacitor to GND for stability (remote placement supported). In shutdown (EN low) an internal ~230-Ω pulldown discharges this pin to GND. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 494 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.
