**TECH PUBLIC** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPMIC5219-2.5YM5 from TECH PUBLIC, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input of supply voltage, recommended 2.0V to 20V (absolute maximum -0.3V to 22V relative to GND). |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable control input. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Output of the regulator, fixed 2.5V for this variant (absolute maximum -0.3V to 6.0V relative to GND). |
