XDS · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT89-3
TX7550-M from XDS, in a SOT89-3. 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 | VSS | power_in | Ground pin (VSS/GND); all voltages are referenced to VSS. |
| 2 | VIN | power_in | Input supply pin, rated up to 40V operating (55V max), needs at least a 1uF ceramic bypass capacitor. |
| 3 | VOUT | power_out | Regulated 5.0V output (±2%) for the 7550, up to 100mA, needs at least a 1uF ceramic output capacitor. |
