TPS73133DBVR 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. Operating range 1.7 V to 5.5 V (absolute max 6 V). Provides power to the regulator's NMOS pass element. |
| 2 | GND | power_in | Device ground reference. Ground pin current is typically 400 uA at Iout = 10 mA and 550 uA at Iout = 150 mA. |
| 3 | EN | input | Enable input. Drive high (>=1.7 V, up to Vin) to turn on the regulator; drive low (<=0.5 V) to place the device in shutdown (Ignd typically 0.02 uA). May be tied to IN if not used. |
| 4 | NR | passive | Noise-reduction pin (fixed-voltage versions only, applies to TPS73133). Connecting an external capacitor (typ. 0.01 uF) to this pin bypasses the internal bandgap reference to reduce output noise to ultralow levels (~8.5 uVrms with Cnr = 0.01 uF). |
| 5 | OUT | power_out | Regulated output. Fixed 3.3 V (TPS73133), 150 mA max output current. No output capacitor required for stability; stable with capacitors of any type/ESR. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 565 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.
