**TECH PUBLIC** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

TPAP2205-33Y from TECH PUBLIC, in a SOT-89-3. 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 30V (absolute maximum -0.3V to 32V relative to GND). |
| 2 | GND | power_in | Ground. |
| 3 | VOUT | power_out | Output of the regulator (fixed 3.3V for the -33 option, up to 200mA); absolute maximum -0.3V to 6.0V relative to GND. |
