SD5088A28E from SHOUDING, 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 | Vss | power_in | Ground pin of the regulator. |
| 2 | Vin | power_in | Voltage input; maximum input voltage is 6.5V, and the device is specified with Vin = Vout+1V. |
| 3 | Vout | power_out | Regulated voltage output (2.8V ±2% for the A28 option) delivering up to 300mA, with Vout limited to Vss-0.3V to Vout+0.3V. |
