LPV521MGX from Texas Instruments, in a SC-70-5. 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 | OUT | output | Amplifier output. Rail-to-rail output, can source/sink ~1 mA (typ 3 mA) with output swing within ~2 mV of either supply rail into RL = 100 kΩ. |
| 2 | V- | power_in | Negative power supply (typically GND for single-supply operation). Total supply voltage V+ − V- must be 1.6 V to 5.5 V. |
| 3 | IN+ | input | Noninverting input. Rail-to-rail common-mode input range (0 V to V+); input bias current typically 40 fA. Must stay within V- − 0.3 V to V+ + 0.3 V. |
| 4 | IN- | input | Inverting input. Rail-to-rail common-mode input range (0 V to V+); input bias current typically 40 fA. Must stay within V- − 0.3 V to V+ + 0.3 V. |
| 5 | V+ | power_in | Positive power supply. Operating voltage range 1.6 V to 5.5 V (relative to V-); absolute maximum 6 V. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 380 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.
