TPMIC5233-3.3YM5 from TECH PUBLIC, 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 | VIN | power_in | Input supply voltage. Operating range 3.5V to 36V (absolute max 40V). Requires a 1µF ceramic input capacitor (CIN) to GND. |
| 2 | GND | power_in | Ground reference for the regulator. Common return for VIN, VOUT, and EN. |
| 3 | EN | input | Enable control input. Drive high (VIH ≥ 2V) to enable the regulator; drive low (VIL ≤ 0.6V) to shut down (ISD typ 0.01µA). EN input current typ 10nA at VEN = 36V. Do not float. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net; not electrically connected to the die. |
| 5 | VOUT | power_out | Regulated output of the LDO. Fixed 3.3V ±2%, up to 200mA output current (300mA typ current limit). Requires an output capacitor with effective capacitance ≥ 1µF (ceramic or tantalum) for stability. Dropout typ 0.75V at IOUT = 100mA for VOUT = 3.3V. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 673 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.
