LDK320ADU33R from STMicroelectronics, 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 | GND | power_in | Common ground connection. |
| 2 | IN | power_in | Input voltage of the LDO; operating range 2.5 V to 18 V with 100 mV typical dropout voltage at 100 mA load. |
| 3 | OUT | power_out | Fixed output voltage of 3.3 V with ±0.5% accuracy at 25 °C, supporting up to 200 mA output current. |
