TPMIC5219-3.3YM5 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. Recommended operating range 2.0V to 20V (absolute max 22V referenced to GND). Bypass with a 1µF ceramic capacitor to GND close to the pin. |
| 2 | GND | power_in | Device ground reference. Return path for the internal bandgap, error amplifier, and output current. |
| 3 | EN | input | Enable control input. Drive above VIH (1.1V min) to enable the regulator; drive below VIL (0.4V max) to shut down (ISD ≈ 0.01µA). EN input current is typ. 10nA at VEN=27V. Do not leave floating. |
| 4 | NC | unconnected | No internal connection. May be left floating or tied to GND for mechanical stability. |
| 5 | VOUT | power_out | Regulated output of the LDO. Fixed 3.3V (±2%) at up to 500mA output current with 0.42V typical dropout at 100mA. Requires a 1µF ceramic or tantalum output capacitor to GND for stability. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 630 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.
