DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
DS8404-50A3 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 | VIN | power_in | Input of supply voltage, recommended 2.5V to 36V (absolute maximum 40V), with a 1uF or larger input capacitor placed close to VIN and GND. |
| 2 | GND | power_in | Ground pin; input and output capacitor grounds should return to it with short, wide copper traces. |
| 3 | VOUT | power_out | Regulated 5.0V output (DS8404-50) for up to 500mA peak load current, absolute maximum 14V to GND, requiring an output capacitor of 1uF to 22uF. |
