DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
DS8367-50A3 from DSTECH, 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 | Ground reference for the regulator; the input and output capacitor ground connections must return to this pin using as wide and short a copper trace as practical. |
| 2 | VIN | power_in | Input of supply voltage, specified from 2V to 36V, with a 1µF or larger input capacitor placed close to the VIN and GND pins. |
| 3 | VOUT | power_out | Output of the regulator, which is current-limited to 300mA typical and can be shorted to ground indefinitely without damage. |
