STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
LDK320ADU30R 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 terminal establishing 0 V reference potential for all circuit voltage measurements. |
| 2 | IN | power_in | Input voltage supply terminal; operates from 2.5 V to 18 V DC; bypass with 1 μF capacitor for stability. |
| 3 | OUT | power_out | Regulated output voltage nominally 3.0 V ±0.5% at 25°C, supplying up to 200 mA with internal current limiting and thermal shutdown at 160°C. |
