TLV70033DDCR 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 supply pin. Operating input voltage range is 2.0 V to 5.5 V (absolute max -0.3 V to +6.0 V). A 1-μF ceramic capacitor is recommended from IN to GND to assure stability and good transient performance. |
| 2 | GND | power_in | Ground reference pin. Ground pin current is typically 31 μA (IOUT = 0 mA). |
| 3 | EN | input | Enable input. Driving EN above 0.9 V turns on the regulator; driving EN below 0.4 V puts the device into shutdown, reducing operating current to ~1 μA. Absolute max VEN = -0.3 V to +6.0 V; IEN typ 0.04 μA. |
| 4 | NC | unconnected | No connection. May be tied to ground to improve thermal dissipation. |
| 5 | OUT | power_out | Regulated output voltage pin (3.3 V nominal for TLV70033). Rated for up to 200 mA with a typical dropout of 175 mV at 200 mA. A 1-μF ceramic capacitor from OUT to GND is required to assure stability. |

Two STEP files. Same geometry, different body top:

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 525 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.
